As a leading world supplier of specialty and industrial gases, Air Liquide is all about molecules that matter

Our technologies are carefully engineered to provide customers with meticulouslyanalyzed measures of certain molecules in the form of pure or mixed gases andliquids. These molecules are in turn used as raw materials or end products in them-selves, as is often the case in healthcare or food and beverage processing. Othertimes the molecules we provide are used to measure or test for the presenceof other molecules, as in applications such as environmental monitoring, homelandsecurity or process control.

Our focus however, goes well beyond the refining and selling of molecules. Itincludes providing definable value that can be measured at the bottom line. Aboutone third of Air Liquide’s product sales can be linked directly to applications thatare helping to preserve our environment or ensure human safety. Other Air Liquideproducts and services involve helping our many customers keep pace with achallenging global economy—by empowering them to improve efficiencies with-out sacrificing end product quality or analytical accuracy.

Our commitment to safety, technology and innovation has kept Air Liquide at theforefront of the high-tech business of specialty and industrial gases for more than100 years. Our presence of over 43,000 employees in 75 countries enables usto leverage the resources of a truly global enterprise with powerful, personalizedservice from our localized, customer-focused teams. Combined with innovativeproducts and services, we believe this to be a winning formula that transformsmolecules that matter into greater customer satisfaction, efficiency, growth andsuccess—plus a safer and cleaner environment for us all.

PackagingCylinders for Every Application

Air Liquide provides a wide variety of cylinders selected to meet specific customer needs. In that we producemany gases with widely varying chemicalcharacteristics, appropriate package offerings must be based on several keycriteria.

Safety The safety of each and every customer,as well as that of those who handle or transport our products, is of the utmost importance. Selection of the correct container and the proper valve is determined by guidelines from CGA, DOT and TC, as well as our ownextensive experience and expertise.

Stability Since specialty gases can be corrosiveor reactive in nature, we carefully matchcylinder and valve types in order to protect the integrity of the gas. To ensuregas mixture stability, reactive gases areonly provided in cylinders treated withour exclusive suite of ACULIFE™ cylinderinerting processes – see page 84 formore information.

Customer Convenience For most gases, the choice of container depends upon your application require-ments. We offer many different cylinders,as well as multi-cylinder packs, tube trailers or even cryogenic liquid containersfor atmospheric and helium pure gases.

PURES AND OTHER SUPPORT GASESALPHAGAZ Pure Gases


Choosing the right gas products for a particular analytical instrument andapplication can be confusing. Air Liquide has simplified gas selection byreducing the complex and confusing matrix of available gas grades downto two levels of purity as represented in our ALPHAGAZ product line. Instead

of focusing on the total purity of the gas, we set limits on the critical impurities that affect theperformance of the instrument and application used.

Three Grades, Two Purity Ranges

An Air Liquide research and development team surveyed major analytical instrument man-ufacturers to determine the recommended gas purity for their instrumentation. Studies werethen conducted on many of these instruments to determine the effect of varying levels ofimpurities on their performance. Our findings indicated that two basic ranges for gas purityare necessary to ensure optimal performance of analytical instruments in most applications.

ALPHAGAZ 2: The Highest Purity Level PossibleALPHAGAZ 2 products exhibit the absolute lowest impurity levels available in the industry,making them the best choice for laboratory, analytic and process control applicationswhere uncompromised ultra-high-purity is needed.

ALPHAGAZ 1: One Convenient Grade for Many ApplicationsALPHAGAZ 1 products exceed purity recommendations of most laboratory instrumentmanufacturers, making them an obvious choice for all-around use in the laboratory. Becausethey provide guaranteed low impurity levels, ALPHAGAZ 1 pures are ideal for most analyticand process control applications, including petrochemical, secondary electronics andoptoelectronics as well as scientific research and many other applications.

ALPHAGAZ 1000: Cryogenic SolutionsALPHAGAZ 1000 provides the same specifications as ALPHAGAZ 1, but is offered for thoseapplications requiring cryogenic liquid argon, nitrogen and helium. Since large volumes ofgaseous nitrogen or argon are needed for ICP and FTIR instruments, cryogenic supplies canbe better suited than cylinders of compressed gas to fill this need. Liquid helium is oftenused to cool magnets in instruments such as NMR spectrophotometers.

Benefits and Features■ Guaranteed low impurity levels protect instrument sensitivity ensuring peak

performance.

■ Residual Pressure Valve (RPV) integrated to prevent atmospheric contamination.

■ Cylinder-to-cylinder consistency provides added performance reliability.

■ Helps reduce cylinder inventory by eliminating need for supplemental pure gases.

■ Color-coded cylinder shoulders for fast, positive visual ID of cylinder contents.

■ Weatherproof and tear-resistant identification label on each cylinder or pack accuratelyindicates impurities.

■ Lot number on each cylinder is traceable to our analytical records for added reliability.

■ Exclusive SCANDINA™ cap and SMARTOP™ valve (see sidebar).

Our customers get the best quality possible for every pure gas we deliver

ALPHAGAZ™ ensures a perfect match for your instrument and application

Chemiluminescence Detector (CD) These detectors are affected by the presence of tracelevels of the specific compounds that they are designed to measure. For example, tracelevels of sulfur often cause a shift in response.

Discharge Ionization Detector (DID) Trace levels of oxygen, moisture and hydrocarbonscan reduce detector response and affect baseline stability.

Electron Capture Detector (ECD) Moisture and oxygen in carrier gas can reduce responseof the detector. Trace halocarbons in the nuclear counter gas (P-5 mixture) can cause base-line shift or negative peaks.

Flame Ionization Detector (FID) Hydrocarbons in carrier gases, fuel gases and oxidizergases can decrease detector sensitivity and reduce the life of the detector. Trace oxygenand moisture in the carrier gas can damage chromatographic columns.

Fourier Transform Infrared Detector (FTIR) Impurities present in the carrier gas with ab-sorbance bands at the same wave length as the species being measured can result ininaccurate response. Moisture and oxygen can interfere with IR spectra.

Helium Ionization Detector (HID) Trace levels of hydrocarbons, oxygen or moisture canaffect detector stability.

Mass Spectroscopy Detector (MS) Impurities with atomic mass at the equivalent of thespecies being measured can result in inaccurate response.

Pulsed Discharge Electron Capture Detector (PDECD) Moisture and oxygen in carrier gascan reduce response of the detector. Trace halocarbons in the nuclear counter gas (P-5mixture) can cause baseline shift or negative peaks.

Pulsed Discharge Helium Ionization Detector (PDHID) Trace levels of oxygen, moistureand hydrocarbons can reduce detector response and affect baseline stability.

Pulsed Discharge Photo Ionization Detector (PDPID) Trace levels of oxygen, moistureand hydrocarbons can reduce detector response and affect baseline stability.

Photo Ionization Detector (PID) Trace levels of oxygen, moisture and hydrocarbons canreduce detector response and affect baseline stability.

Pulsed Flame Photometric Detector (PFPD) Trace levels of oxygen, moisture and hydro-carbons can reduce detector response and affect baseline stability. Contaminants in flamefuel and oxidizer can interfere with detector response.

Did you know?

The first neon sign in America appeared in 1923 when Earle C. Anthony purchased two signs from theFrench company, Claude Neon, to hang outside his Los Angeles car dealership. Somewhat sedateby today’s standards, they simply read, “Packard.” French engineer, chemist and inventor, GeorgesClaude, who cofounded Air Liquide in 1902, displayed the first neon lamp on December 11, 1910 inParis and was granted a U.S. Patent (1,125,476) for his invention on January 19, 1915.

The Issue of Purity

Air Liquide does not use low quality raw materials of lower purity, primarily because increasedimpurities are known to create application problems such as unidentified peaks on chro-matographs. We insist on using only the highest purity components available, and stockmore than 800 high-purity components for use in making our gas and liquid standards.

Our Capabilities

The number of possible gas and liquid mixtures consisting of various components in vary-ing concentrations is nearly infinite. Therefore, this section is only a guideline containing manyof the more commonly requested mixtures we produce. Additional mixtures not shown inthis catalog are available, as are custom developed products for very specialized applica-tions. Nonetheless, despite being the world leader in specialty gases, we do encountercertain limitations that preclude production of certain mixtures. Some are safety-related whilemost are a matter of chemistry.

SCOTT mixtures have long been the definitive standard for calibration accuracy. OurISO/IEC 17025 certified laboratories follow strict procedures for preparation and analysis of gas mixtures, thus ensuring traceable products of the highest quality. When appropriate,our calibration mixtures are analyzed against benchmark standards such as StandardReference Materials (SRMs) obtained from the National Industrial Standards and Technol-ogy (NIST) or other recognized suppliers such as VSL (formerly NMi) in The Netherlands.Air Liquide maintains the world’s largest inventory of NIST-Traceable Reference Materials(NTRMs), which we use in the production of mixtures.

How Gas Mixtures are Prepared, Analyzed and Certified

GRAVSTAT™

Gas mixtures are blended by a number of different methods. The most common method isto gravimetrically weigh each component of the mixture using a scale routinely calibratedagainst NIST weights, resulting in a mixture traceable to NIST. Our GRAVSTAT process yieldsresults often considered to have less uncertainty than analysis against other reference stan-dards, which is particularly true for mixtures containing nonreactive components at percentlevel concentrations.


SCOTT RATA Class™ and Compliance Class™ environmental protocol gas mixtures aredual-analyzed using EPA G1 or EPA G2 methods. Two independent analyses are performedafter the blending process has been completed in order to determine the concentrationfor each component contained in the mixture and these analyses must agree to within±1%. RATA Class mixtures are always directly traceable to metrology institute standards,yielding the highest accuracy possible and enhancing RATA test performance.

SCOTT Reference Class™ mixtures are dual-certified and are the most accurate mixtures foryour calibration needs. They receive two rigorous, independent methods of certification, oneduring gravimetric blending using our GRAVSTAT™ process and the other using proprietarylaboratory analytical procedures. Each of these processes yields an accurate concentrationfor each component. We then further ensure the accuracy of your mixture by employing ourexclusive interlocking feature: the concentrations determined from both certificationprocesses must agree (interlock) with each other within 1%. Both blending and laboratoryprocesses are traceable to recognized metrology organizations or internally developedAir Liquide Reference Standards (ALRSs). These standards help you to improve the value of your end product by facilitating precise instrument calibration accuracy, tighter processcontrol and credibility.


Single-certified standards provide the certified concentration from one independentmethod—either the blending process or laboratory analysis. Specifications are achievedby the accuracy and traceability of the blending process or the laboratory analysis.

Air Liquide offers three choices for single-certified standards:




Single-certified standards can be used for primary calibration of instrumentation. They arealso frequently used as validation standards after the instrument is calibrated with a dual-certified standard such as a Reference Class product.

Custom Standards

A discussion of SCOTT gas and liquid mixture products would not be complete withouthighlighting the availability of custom standards—custom mixtures engineered to yourspecifications. The manufacturing of custom standards is a tradition, reflecting our abilityto blend mixtures specifically designed to successfully meet your applications. See page14 for a listing of components available for blending.

InterlockedConcentrations ±1%

Interlocking Concentration Values

These values provide the highest possibledegree of accuracy in a calibration standard. The concentration value determined during the blending processis compared with an independent concentration value obtained throughlaboratory analysis after the blending has been completed. Interlocking valuesoccur when both values agree within±1% of each other.

Interlocked concentration values areavailable exclusively from Air Liquide andrepresent the utmost level of accuracyand confidence available in any calibrationstandard.

All Reference Class products are providedwith interlocked concentration values.


GAS AND LIQUID MIXTURESUnique SCOTT Technology


Unique SCOTT™ TechnologyAir Liquide’s commitment to continuous innovation in specialty gas technology has resultedin an impressive portfolio of mixing, blending and analysis capabilities. These technicalinnovations, coupled with 100 years of experience in the business, allow us to achieve un-equalled product specifications, regardless of the nature of the components in the mixture.Certain technologies and product attributes are only available from Air Liquide.

Guaranteed Mixture Stability Begins with ACULIFE™

SCOTT ACULIFE is a suite of proprietary cylinder inerting treatments, utilized to enhancethe stability of reactive gas and liquid mixtures. These chemical vapor deposition processeseliminate gas-to-cylinder surface interactions to provide guaranteed stability for ppm andsub-ppm calibration standards, making possible a variety of unique and innovative products.For example, Air Liquide is the leading supplier of hydrogen sulfide in air mixtures, withguaranteed stability for safety and industrial hygiene applications. We also have uniquehydrogen chloride gas standards in the low ppm range, made possible by ACULIFE.

SCOTT ACUBLEND™ Produces Zero Blend Tolerance

ACUBLEND can produce a gas mixture having a unique feature called Zero Blend Tolerance.Zero blend tolerance means no difference between certified and requested concentration.The process is also capable of preparing a gas mixture precisely within a specified blendtolerance. ACUBLEND enables Air Liquide to produce identical and homogeneous gasmixtures in as many separate cylinders as desired. Identical gas mixtures in separatecylinders have proven valuable by permitting the user to connect such cylinders to a com-mon manifold, or allowing cylinders having identical concentrations to be used in separatework areas.

ACUBLEND gas mixtures of identical concentration are ideally suited for 6-pack service.Typically, customers using this service consume gas from four cylinders (through a commonmanifold) that leaves the remaining two cylinders available for emergency and additionalsupply until the 6-pack is replaced with another of identical concentration.

SCOTT MICROGRAV™ Enables PPT Concentrations

Air Liquide is the only specialty gas manufacturer to prepare and certify accurate and stablegas mixtures containing compounds with concentrations approaching parts-per-trillion(ppt) levels in returnable and nonreturnable cylinders. Our MICROGRAV process is a directblending technique that eliminates inaccuracies inherent in serial dilution methods.

Analytical quality control with proven gas chromatographic techniques verifies the accuracyof MICROGRAV mixtures. ACULIFE inerting cylinder treatment provides one year guaran-teed stability for mixtures in a nitrogen balance gas. Air Liquide is the primary supplier ofMICROGRAV gas mixtures to NIST and the EPA, as well as to state and other governmentagencies. For available MICROGRAV mixtures, contact your Air Liquide representative.

Benefits of Using SCOTT ACUBLEND Mixtures

■ Short production time results in fast delivery.

■ Identical concentrations can be usedwith multiple process streams at variouslocations to ensure identical calibration.

■ Zero Blend Tolerance results in receivingexactly the concentration you ordered.

■ Completely homogeneous mixtures improve the accuracy and dependabilityof ACUBLEND mixtures.

■ A virtually unlimited supply of identicalmixtures—from cylinder-to-cylinder andbatch-to-batch—eliminates the need forrecalibration due to variations in mixtureconcentrations.

UNIPHASE™ Liquid Mixtures

Many applications require mixtures containing low vapor pressure and liquid components.These may be components that are in the liquid phase at normal atmospheric temperaturesand pressures, or they may be components that are in the liquid state at the concentrationand pressure desired in the container. Liquid mixtures can be prepared two ways. In thefirst, the blend is made in a conventional cylinder in which the components exist in thecylinder under their own vapor pressures. In this type of mixture a dip tube, allowing with-drawal from the bottom of the container, is usually provided. The withdrawal of the liquidphase minimizes the concentration changes that will occur during emptying of the cylinderdue to fractionation of the more volatile components.

In the second method, the mixture is made completely in the liquid phase using a floatingpiston cylinder to preserve mixture integrity. Such mixtures are called UNIPHASE. UNIPHASEliquid mixtures are highly recommended when mixture components possess significantlydifferent vapor pressures and solubility characteristics. Air Liquide provides a Certificateof Accuracy with detailed BTU calculations for all UNIPHASE mixtures. Phase envelopesare available upon request. Air Liquide representatives will advise you when UNIPHASEpiston cylinders are necessary to ensure a single phase mixture.

SCOTT GRAVSTAT™ Gravimetric Blending

Mixtures that are prepared gravimetrically are produced by weighing the gas componentson a high-load, high-sensitivity analytical balance. Air Liquide uses NIST or VSL weights forthis procedure to assure mixtures are traceable to a reference standard that is certified by anational or international metrology organization. Our gravimetric process, GRAVSTAT™, takesinto account all statistical parameters including scale weight uncertainty, scale calibrationand the raw material impurities of all pure components in multi-component mixtures. As aresult of GRAVSTAT, Air Liquide can assert the process accuracy by calculating gravimetricuncertainty and properly representing the true value of component concentration.

Mixture Safety

Air Liquide carefully engineers every mixture to assure that the mixture can be made safelyand reliably. Gas mixtures containing both oxidizing and reducing agents, such as thosecontaining a fuel plus an oxidizer, can be safely prepared but only if the concentration ofthe flammable component lies outside the flammable range. Since a flammable rangevaries with temperature and pressure, it is difficult to state a specific rule concerning thepreparation of these mixtures. Air Liquide uses sophisticated engineering software to per-form the necessary calculations. Generally, a mixture containing a flammable gas and anoxidizer can be prepared at reduced pressures if the concentration of the flammable com-ponent is less than 50% of the lower flammable limits.

SCOTT™ Interference-Free™ Multi-Component Protocol Gases

With the advent of acid rain legislation, Air Liquide pioneered the development of Interference-Free multi-component protocol gases. This innovation set a new industry standard byallowing utilities to switch to multi-component protocol gases in order to save time and moneyin calibration auditing and cylinder handling. Interference-free technology also alleviated theconcern regarding mixtures of sulfur dioxide, nitric oxide and carbon dioxide where highconcentrations of CO2 can interfere with NO analysis on certain traditional analytical instru-mentation. This interference-free technology is built into every RATA and ComplianceClass™ multi-component product.

RATA Class™ Protocol Gases: Most Accurate Protocol Available

SCOTT RATA Class protocol gases are recommended for all environmental applicationsrequiring the highest degree of compliance certainty, including:

■ Primary calibration

■ RATA tests

■ Linearity tests

■ CGAs and audits

RATA Class protocol mixtures are engineered to achieve ±1% accuracy, which makes RATAClass protocol gases especially valuable for Relative Accuracy Test Audits. Many utilitiesand other industrial facilities are pushing the performance of their continuous emissionsmonitoring systems (CEMS) far below the ±10% RATA requirement of the EPA’s AcidRain Program to save the $30,000 – $70,000/year cost for RATA testing by achieving theEPA ±7.5% accuracy limit. The RATA Class protocol is a critical element in achieving thesesavings. This class also provides accurate measurements of SO2 and NOx emissionsthereby facilitating emissions trading credits where allowed.

RATA Class mixtures are dual-analyzed. For each reactive component, two separate analy-ses are performed and analyzed directly against metrology institute standards to determinethe concentrations. Air Liquide’s proprietary analytical technology created the capabilityfor these two measurements to agree with each other within ±1%, even in two, three orfour-component mixtures. An easy-to-read Certificate of Accuracy is provided with eachRATA Class mixture as illustrated on page 90.

Compliance Class™ Protocol Gases: ±2% Accurate

SCOTT Compliance Class protocol gases meet EPA requirements for less demandingenvironmental measurements. Compliance Class mixtures also feature dual-analysis andNIST standard traceability. A Certificate of Accuracy is provided with each ComplianceClass mixture.

Cost-Effective and Dependable Calibration

Reference Class mixtures are appropriatein applications such as hydrocarbon processing, where high-accuracy calibra-tion is of prime importance. This productassures reproducibility of your particularmixture over time. Every subsequent Reference Class product you receive inthe future is guaranteed to calibrate within±1% of your original mixture.

SCOTT Reference Class mixtures are engineered to provide ±1% accuracy. They are gravi-metrically prepared using GRAVSTAT™, dual-certified, and they are available in a widerange of components and concentrations. Reference Class mixtures are guaranteed to betraceable to NIST, VSL or Air Liquide Reference Standards (ALRSs), which in many casesare the only established reference materials in the world.

The Air Liquide Interlock Advantage

Reference Class mixtures receive two rigorous, independent methods of certification, oneduring gravimetric blending using our GRAVSTAT process, and the other using proprietarylaboratory analytical procedures from Air Liquide. Each process yields an accurate concen-tration for each component. These independent concentrations are then interlocked – theymust agree with each other to within ±1%.

Our exclusive interlocking feature allows for two independent determinations of the trueconcentration of each component to be built into every mix. These independent measuresconfirm one another, and therefore guarantee that our certification processes are unbiased.Interlocking concentrations work to your advantage allowing you to perform extremelyprecise instrument calibrations that will not drift over time. As a result, you can exert tighterSPC control limits on processes.

Air Liquide provides a detailed Certificate of Accuracy with every Reference Class mixture asshown on the next page. The analyzed concentration is reported for each minor component.In mixtures with a concentration above 2%, the GRAVSTAT-determined concentration isreported and the analyzed concentration is shown. In addition, the requested concentrationis shown and the Certificate of Accuracy also documents the traceability and shelf life.

Benefits and Features■ Dual-certification, independent blending and laboratory analytical values

guarantee the accuracy of your mixture.

■ Air Liquide’s exclusive, interlocked concentration values permit precise calibrations that will not drift over time, allowing tighter SPC.

■ Air Liquide Reference Standards (ALRSs) provide traceability over the widest range of components and concentrations available in the industry.

■ Guaranteed ±1% accuracy minimizes uncertainty in critical primary calibration applications.

■ Produced using GRAVSTAT, a gravimetric gas metering methodology for proven reliability.

■ Assured availability from Air Liquide’s regional manufacturing facilities provides just-in-time delivery to minimize the need for on-site inventory.

GAS AND LIQUID MIXTURESSingle-Certified Standards

ACUBLEND products have been a specialty gas industry standard for over 30 years. Morecalibration gas mixtures have been manufactured by ACUBLEND than any other process.Many customers have come to depend on the homogeneity, consistency and repeatabilityof ACUBLEND mixtures for their ongoing, close tolerance calibration needs.

SCOTT ACUBLEND Master Class mixtures are produced using our patented ACUBLENDand FLEXBLEND™ gas blending and analysis technologies. These unique processes allowAir Liquide to blend, mix, compress and analyze gas mixtures in a single operation usingeither gas or liquid phase minor components. Because the ACUBLEND and FLEXBLENDprocesses are so tightly controlled, the cylinders produced from them are completely homogeneous from top to bottom within the cylinder, from cylinder-to-cylinder, and evenfrom batch-to-batch. Each cylinder contains a mix that has a single-certified analytical concentration, accuracy and traceability when the blending is finished.

Dynamic Blending Using Proprietary Reference Standards

ACUBLEND Master Class mixtures are dynamically blended using high resolution, real-timeanalyzers. We use NIST or Air Liquide Reference Standards (ALRSs) for primary calibrations.Air Liquide employs extensive, proprietary calibration algorithms to control our analyzersand achieve an analytical accuracy of ±1% or ±2%, depending on the concentration rangeyou choose.

SCOTT ACUBLEND Master Class mixtures are backed by our state-of-the-art process con-trols and include those mixtures where our knowledge of real-time sensors and calibrationtechniques has demonstrated that an interference-free measurement can be made in realtime and within our analytical accuracy specifications. As with our other product classes,raw materials are carefully selected and verified to purity specifications prior to use in theACUBLEND process.

Air Liquide provides a detailed Certificate of Accuracy with every ACUBLEND Master Classmixture as shown on page 94. The analyzed concentration is reported for each minorcomponent. In addition, the requested concentration can be shown.

Benefits and Features■ Short production time results in fast delivery.

■ Identical mixture concentrations can be used with multiple process streams at various locations to ensure identical calibration.

■ Zero Blend Tolerance results in receiving exactly the concentration you ordered.

■ Completely homogeneous mixtures improve the accuracy and dependability.

■ A virtually unlimited supply of identical mixtures—from cylinder-to-cylinder and batch-to-batch—eliminates the need for recalibration due to variations in mixture concentrations.

Recommended Applications■ Calibration for multiple users

■ Auto emissions test cells

■ Multi-facility calibrations

■ Long-term or recurring calibrations

■ Homogeneous consumable processmaterials

■ Applications requiring large volumes of a given mixture

Zero Blend Tolerance

Upon request, ACUBLEND Master Classmixtures can be manufactured with a unique attribute we call Zero Blend Tolerance. Zero Blend Tolerance simplymeans “no deviation from ordered concentration,” in that the concentrationwe produce for you is the same as theconcentration you requested.

Zero Blend Tolerance is a very usefulfeature for those applications where youneed a calibration standard at an exact,specified concentration, or where a new calibration standard that you ordermust match up exactly with your existingACUBLEND Master Class mix currently inuse. Repeat orders can perfectly duplicateprior orders and cylinders can be inter-changed with no harm to your process.

SCOTT Certified Class mixtures offer the largest selection and combination of components,concentrations, balance gases and cylinder options. You may choose from any compo-nents listed on pages 14 and 15, or contact Air Liquide to discuss your custom applica-tions. Components can be blended into a variety of balance gases, such as the traditionalnitrogen, air or helium. The Certified Class mixtures even offer you the option of blendingcomponents into difficult hydrocarbon gas and liquid phases such as methane, ethyleneor liquefied petroleum gas (LPG).

In Certified Class, both reactive and nonreactive components are available in almost anyconcentration range, and with one, a few or a large number of components, limited onlyby the physical properties and chemical reactivities of the components themselves. Air Liquide has successfully produced mixtures with more than 100 components to meetspecialized customer needs.

Certified Master Class™ Mixtures

Certified Master Class mixtures are blended using high-accuracy gravimetric, volumetric orour patented ACUBLEND™ and FLEXBLEND™ techniques, depending on the components,concentrations and combinations you select. This class of mixtures is single-certified, thatis, the stated (certified) concentration is determined from either the blend process or frominstrumental analysis. For Certified Master Class mixtures, the accuracy of the certifiedconcentration is typically ±1% or ±2% depending on the concentration range you select.While some suppliers offer gas mixtures they refer to as being “certified,” Air Liquide’sCertified Master Class mixtures feature both guaranteed concentration and accuracy foreach component in your mix. As a result, you can be certain that your Certified Class mix-ture meets Air Liquide specifications.

Certified Master Class products provide you flexibility in component selection. Raw materialsare carefully selected and analyzed to control impurities prior to use, even in cases whererare, unusual or customer provided materials are used. Further, and prior to manufacture,Air Liquide conducts extensive engineering for every Certified Class mixture to assure thateach mixture can be prepared safely and that no uncontrolled cross-contamination orcross-interference will occur.

Air Liquide provides a detailed Certificate of Accuracy with every Certified Master Classmixture. The certified concentration is reported for each minor component. In addition,the requested concentration can be shown indicating the blend tolerance specificationordered, a useful feature for reordering. Every Certified Master Class Certificate of Accuracyalso documents the process traceability and shelf life. A sample certificate is shown onpage 97.

Fuel Gas BTU Analysis

In-plant heating and power generationprocesses represent one of the biggestoperating costs faced by refineries, petro-chemical and chemical plants. Accuratedetermination of the BTU content of fuelgas is an important facet of controllingenergy costs. By using SCOTT CertifiedClass mixtures, many oil and chemicalcompanies have reduced their energycosts through accurate determination ofthe BTU content of their fuel gas streams.For custody transfer or sales applications,we recommend using Reference Classmixtures.

Fired Heater and Furnace Optimization

SCOTT Certified Class mixtures may beused to accurately analyze the levels ofoxygen, carbon monoxide and unburnedhydrocarbons contained in the exhaustgases from fired heaters and crackingfurnaces. With out accurate analysis andproper control of these components, a plant’s energy costs would skyrocket.Certified Class mixtures will help you reduce your energy costs by providingyou with an accurate analysis so that you can better control these critical unitoperations.

Certified Working Class™ Mixtures

SCOTT Certified Class mixtures are used in a wide variety of laboratory and online instru-mentation applications such as primary calibration and validation under statistical processcontrol (SPC). Your specific requirement will drive the choice of class.

Air Liquide selects the appropriate high-accuracy gravimetric, volumetric or dynamic processto blend your Certified Working Class mixture, depending on the components and con-centrations you select. Working Class mixtures are single-certified, and the accuracy of thecertified concentration ranges between ±2% to ±5%, depending on the concentration rangeyou select.

Certified Working Class products also provide you with tremendous flexibility in componentselection and combination. Air Liquide practices the same careful raw material quality con-trol and preblend engineering as used in Certified Master products to assure a reliable andsafe mix. An added benefit, depending on your specific needs, is that a Certified WorkingClass product may actually be available at a lower concentration or for a more reactivecomponent than for the corresponding Certified Master Class, because of the wider tol-erances allowed by the Certified Working Class specifications.

Air Liquide provides a detailed Certificate of Accuracy with every Certified Working Classmixture. The certified concentration is reported for each minor component. In addition, therequested concentration can be shown indicating the blend tolerance specification, a usefulfeature for reordering. Every Certified Working Class Certificate of Accuracy also documentsthe process traceability and shelf life.

Pushing the Technical Envelope

When your specialty gas application has challenging specifications, Certified Class Mixturesfrom Air Liquide are an excellent choice. No other specialty gas manufacturer combinesleading-edge mixture specifications with such great flexibility in component selection,concentration or combination. When no one else can do it, contact Air Liquide, receivetechnical support and get your job done right.

ENVIRONMENTAL COMPLIANCEExperts in EPA Protocol Gases

You could be risking noncompliance and the expense of unnecessary RATA tests. Considerthese important facts you should know before you purchase another EPA protocol gas.

■ Cost-efficient utilities typically save $30,000–$70,000/year or more in repeat RATA testing by achieving Acid Rain Program relative accuracies below the EPA’s7.5% specification.

■ Direct traceability to SRMs, PRMs and NTRMs is essential for protocol accuracy.

■ Traceability to GMIS standards can degrade accuracy to worse than ±2%.

■ G2 analysis leads to uncertainty and questionable protocol accuracy.

■ Some multi-component protocol mixtures may cost less – at the expense of accuracy.

■ Mathematical corrections, when producing multi-component mixtures, do not providethe same degree of certainty as FTIR technology.

Trust the Experts in EPA Protocol Gases

Air Liquide is the world’s foremost authority and supplier of environmental calibration gases.In fact, we developed the original EPA protocol gases guidelines, were actively involved insubsequent revisions, and currently participate in other important EPA gas calibration guidance. We offer two classes of EPA protocol products that are instrumental in helping industries avoid noncompliance fines and downtime caused by inaccurate instrument calibration.

SCOTT™ RATA Class™ protocol gases are recommended for applications requiring the highest degree of compliance certainty, including primary calibration, RATA tests, and quarterly CGAs and audits. RATA Class protocol mixtures are dual-analyzed and manufactured to achieve ±1% accuracy.

SCOTT Compliance Class™ protocol gases meet EPA requirements for less demandingenvironmental measurements. Compliance Class mixtures also feature NIST standardtraceability. They are dual-analyzed and manufactured to achieve ±2%.

For detailed information about the features and benefits of SCOTT EPA protocol gases, seepages 86 to 89 in the Mixtures section of this catalog.

Partners in Proficiency Testing with Louisiana DEQ

Air Liquide is the only specialty gas supplier authorized by the Louisiana State Departmentof Environmental Quality to supply proficiency testing (PT) samples. Those applying for alicense to perform stack or engine emissions testing in Louisiana must first accurately an-alyze a blind PT sample provided by Air Liquide. The applicant submits their analysis resultsto Air Liquide for evaluation. Air Liquide reviews the analysis and determines a pass/failresult. Once the applicant passes, Air Liquide will generate a Certificate of Analysis for theoriginal PT sample and issue it to the applicant, and submit the results of the PT evaluationto the DEQ.

Beyond Accuracy

SCOTT RATA Class EPA Protocol Gasesdeliver ±1% accuracy which is critical forenvironmental regulatory compliance.However, according to the EPA, you’re stilllikely to fail an environmental audit forthree key reasons.

Air Liquide can protect you againstthese three major pitfalls withSHOP@airliquide™ online inventorymanagement system.

1. No Certificate of Accuracy on FileAir Liquide gives you dependable, 24/7online access to a Certificate of Accuracyfor every protocol in your inventory – you’llnever lose or misplace another certificate.

2. Expired protocol gas in useAir Liquide sends you an email alertingyou when a cylinder in your inventoryreaches its expiration date – you won’t run the risk of inadvertently using a protocol gas that may no longerbe accurate.

3. Cylinder pressure below 150 psiAir Liquide provides the option of sendingemail alerts when the pressure of acylinder in use at your facility reaches lowlevels – you can promptly change out thecylinder before a violation occurs.

SCOTT™ Low NOx EPA protocol gases from Air Liquide are unique in the environmentalindustry. With guaranteed ±1% accuracy in concentrations as low as 0.1 ppm, they providethe highest reliability and level of confidence for meeting environmental compliance require-ments. They are invaluable for use by stack testers and utilities, and can be used forRelative Accuracy Test Audits (RATAs). SCOTT Low NOx EPA Protocol Gases are dual-analyzed using EPA G1 or G2 methods. Two independent analyses are performed after theblending process has been completed in order to determine the concentration for eachcomponent. As per EPA requirements, the values obtained from these analyses must agreeto within ±1%. Air Liquide also manufactures Interference-Free™ Low NOx EPA Protocolswith CO or CO2, creating the only dual-component low NOx protocol gas available today.

Benefits and Features ■ NIST or VSL-traceable.

■ ±1% guaranteed dual-analyzed accuracy.

■ Detailed Certificate of Accuracy meets EPA requirements.

■ Identification of reference standard.

■ Certified for NO, NOx, or both.

■ Interference-Free multi-component mixtures are also available with either CO or CO2 certified.

ENVIRONMENTAL COMPLIANCESCOTT CEM DAILY STANDARDS

161

Air Liquide offers two grades of CEM DAILY STANDARDS. These standards are typically used in applications where the use of EPA protocolgases is not required. Zero blend tolerance is available with our proprietary ACUBLEND™ technology so multiple cylinders are produced at the same concentrations. This minimizes the need to recalibrate from cylinder to cylinder. The following table lists available mixtures forboth grades.

CEM 1% DAILY STANDARDS provide ±1% analytical accuracy to help reduce errors in calibration and linearity. Use these standards tohelp maximize CEM system performance on a daily basis.

CEM 2% DAILY STANDARDS provide consistent ±2% analytical accuracy for those mixtures for which it is not possible to achieve ±1%accuracy. This accuracy is comparable to the ±2% minimum accuracy requirement of an EPA protocol gas mixture. Use these standardsto maximize daily CEM performance in applications where ±1% analytical accuracy is either unavailable or unnecessary.

Mercury Verification ProductFossil-fueled power plants may be monitoring their mercury stack emissions in accordancewith EPA 40 CFR Parts 60 & 75. Thermo Fisher Scientific’s popular Model 80i MercuryAnalyzer uses small amounts of 900 ppm chlorine gas (in nitrogen balance gas) for a weeklyintegrity test of their analyzer system. Drawing on the principle of gas phase titration, ele-mental mercury vapor is combined with dilute chlorine gas from a small cylinder to formmercuric chloride. The mercuric chloride is then injected into the probe filter and throughthe entire system to calculate/confirm the conversion efficiency. This process takes place onthe stack at the point of injection. The chlorine gas is available in a disposable cylinder witha matching regulator per the specifications to the right.

Landfill Gas Applications

Landfill gas (LFG) is composed primarilyof methane and carbon dioxide but alsocontains trace quantities of other Non-methane Organic Compounds (NMOCs).Although these NMOCs represent only a fraction of the total LFG, uncontrolledemissions may exceed the Title V majorsource thresholds for VOCs. Many havebeen designated as Hazardous Air Pollutants (HAPs) under the Clean Air Act,and therefore may be the driving forcefor air regulatory compliance.

Typical Applications for Calibration Standards

■ Monitoring feedstock streams for a chemical process. This may includestandards with trace minor components at ppm or ppb levels with balance gases such as ethylene,propylene or propane.

■ Monitoring intermediate streams in a chemical process. These blendsoften consist of several components,many of which could be present in percent levels.

■ Monitoring recycle streams in a plantprocess. Analyzers are used to determine how to adjust a downstreamprocess to allow for the use of a recycle stream that may be changing.

■ Monitoring waste streams going for disposal.

■ Quality assurance for final productstreams.

■ Measuring natural gas energy (BTUvalue), sulfur and moisture content.

We stock over 800 pure componentsfor blending mixtures used for refiningand petrochemical applications.

Example of a Multi-Component Hydrocarbon Mixture

Consider a hydrocarbon mixture of composition shown below (mole %).

0.2% Ethane3% n-Butane

25% Propane0.3% 1-Butene

68.2% Propylene0.3% Isobutylene

3% Isobutane

The phase envelope diagram belowshows how vaporization and condensa-tion points vary with changes in pressureand temperature. At room temperature (72°F or 22°C), this mixture will start tocondense at about 120 psig (8 bar) andwill be mostly liquid at 135 psig (9 bar).This gas phase mixture would be suppliedin a cylinder at less than 120 psig (8 bar).

A phase envelope diagram also indicatesthe temperature at which the gas phasemixture will start to condense. By exam-ining this diagram, the user will see thatstoring the cylinder outdoors on a coldday may cause the heavier componentsto condense.

Phase envelopes are available upon request – please contact your Air Liquiderepresentative.

Changes in ambient temperature may lead to phase changes with many hydrocarbon cal-ibration mixtures. When a phase change occurs, the resulting composi tion may be differ-ent from the original composition. For a gaseous mixture, heavy components (low vaporpressure) may condense at low ambient temperatures. In liquid mixtures, vaporization ofone or more lighter (high vapor pressure) compo nents will occur as liquid is withdrawnfrom the cylinder, or if ambient temperature increases significantly above the temperatureat which the mixture was made.

Temperature and pressure changes may cause your single phase hydrocarbon mix turesto form two phases. Analytical or calibration work may be inaccurate if a cylin der is usedin which phase changes have occurred. Air Liquide uses computer programs with the mostaccurate equations-of-state to predict the response of hydrocarbon mixtures to temperatureor pressure changes. The benefit of these programs is two-fold:

1. They allow Air Liquide to specify the pressure and temperature at which a mixture can be produced and still maintain a single phase.

2. They alert the customer to potential mixture composition problems due to changes in ambient temperature.

With a database of hundreds of compounds and the ability to expand, Air Liquide canevaluate virtually any mixture. The types of information that can be supplied for a hydro-carbon mixture are as follows:

Gases Maximum pressure or minimum temperature to avoid condensation of one or morecomponents.

Liquids Minimum pressure and maximum tem perature to avoid vaporization of one or morecomponents.

Specified Overall Composition Fraction of mixture that is liquid or vapor and the com-position of each phase.

Phase Envelope Pressure vs. temperature diagrams will provide condensation and/orvaporization curves for a given mixture. These are available upon request.

Engineered to Your Specifications

To ensure mixture integrity and stability, Air Liquide technical representatives evaluatecustom requests and recommend appropriate cylinders in terms of size and construction,ACULIFE™ cylinder treatment if required, and proper gas handling equipment dependingupon the types and concentrations of components in the mixture. Computer programs,as described above, are available to help predict the phase behavior of mixtures.

Analysis for petrochemicals and refining may require the use of liquid blends. Air Liquidehas the know-how to prepare these products for you with guaranteed reliability and quality.

In the case of pure hydrocarbons, the phase (liquid or gas) is determined by the liquid/vaporequilibrium. Therefore, introducing hydrocarbon components into a mixture can affect thephase of the blend and result in technical limitations. Typically, hydrocarbon calibrationmixtures are a combination of many different components having a wide range of boilingpoints. Changes in conditions, such as temperature or pressure, can cause condensationor vaporization of certain components. In such cases, the composition of each sampletaken from the cylinder may differ from its original analysis.

Mixture Composition

To prevent mixture composition from changing as the cylinder is depleted, it is necessaryto limit pressure variations within the cylinder and to take the sample from the liquid phase.Down the line, the product can then be used either as a liquid stream or a gaseous stream.Cylinders containing liquid hydrocarbon blends can be provided with the following uponrequest and based on your application.

Dip Tube Allows the withdrawal of the liquid phase from the cylinder.

Pressurized Cylinder An inert gas maintains a pressure pad inside the cylinder. This keepsthe mixture in the liquid phase and minimizes changes in concentration of the various hydrocarbons in the cylinder headspace.

Dual-Port Valve Combining a dip tube for sampling with a valve for gas pressurization.

Piston Cylinder Used with volatile compounds to guarantee the components remain inthe liquid phase throughout the use of the mixture.

Gaseous Blends Containing Liquefying Components

You may prefer a cylinder containing a gaseous mixture. Keep in mind that this may imposecertain limitations on the concentration of some components and/or on the cylinderpressure. Simply contact your Air Liquide representative with your requirements and wecan advise you.

Our liquefied UNIPHASE™ calibration standards are made with high-puritycomponents that are analyzed prior touse in these mixtures. Liquid blends aretypically prepared gravimetrically usingprecision balances calibrated with weightscertified by NIST. Specific componentsare identified, quantified and reported in the detailed certification that accom-panies each mixture.

Air Liquide has the expertise to produce stable calibration standards that duplicatethe process stream being analyzed.

Liquid Mixtures continued

Standard Cylinder with Single-Port Valve and Precharged Pressure Pad

Liquid mixtures using a standard size cylinder, a single-port valve and a precharged pad aregravimetrically prepared with GRAVSTAT™ using balances calibrated with weights traceableto NIST. The head space above the liquid is initially pressurized (precharged) with an inert gassuch as helium. Liquid is withdrawn from the cylinder using the pressure in the head space.

Advantages This set-up is used with less volatile components (i.e. those with a lowervapor pressure) even though the cylinder pressure decreases as liquid is withdrawn fromthe bottom of the cylinder via a dip tube.

Disadvantages More volatile components (i.e. those with a higher vapor pressure) tend toaccumulate in the inert gas head space. Buildup of volatile components in the head spacelowers the accuracy and consistency of the calibration standard. The total cylinder pressuredeclines as liquid is withdrawn and results in changing sample delivery pressure.

Recommended Uses Adequate for mixtures with components having low volatility.

Standard Cylinder with Dual-Port Valve and Precharged Pressure Pad

Liquid mixtures using a standard size cylinder with dual-port valve and constant pressure padare blended gravimetrically with GRAVSTAT using balances calibrated with weights traceableto NIST. The head space above the liquid is initially pressurized (precharged) with an inertgas such as helium. The head space pressure should be constantly maintained through thedual-port valve using a high-pressure inert gas cylinder. Liquid is withdrawn from the bottomof the cylinder using the pressure in the head space.

Advantages The head space pressure is held constant as the liquid is withdrawn from thebottom of the cylinder via a dip tube.

Disadvantages More volatile components (i.e. those with a higher vapor pressure) tend toaccumulate in the inert gas head space. Buildup of volatile components in the head spacelowers the accuracy and consistency of the calibration standard.

Recommended Uses Adequate for mixtures with components having low volatility andit provides a constant sample delivery pressure.

UNIPHASE™ Floating Piston Cylinder

Liquid mixtures using the UNIPHASE cylinders are gravimetrically prepared with GRAVSTATusing balances calibrated with weights traceable to NIST. The pressure within the piston ismaintained by pressurizing one side of the floating piston with an inert gas such as helium.The floating piston effectively separates the liquid from the inert gas. Liquid is withdrawnfrom the cylinder by maintaining a constant pressure on one side of the piston using theinert gas. The constant pressure on the piston prevents the lighter components fromvolatilizing. When ordering, please specify desired pressure of helium pad. Due to DOTregulations, the cylinder must be shipped in a case. Phase envelope available upon request.

Advantages More volatile components are kept in the liquid phase.

Disadvantages There are essentially no disadvantages to using a piston cylinder.

Recommended Uses Provides the most accurate and consistent liquid phase calibrationstandards available and should be used for all demanding applications such as productsales and custody transfer.

SCOTT™ Certified Class™ BTU mixtures from Air Liquide are the calibration gas of choicefor all natural gas applications. These mixtures are commonly used at custody transfer pointswhen both parties need to agree on the analysis. Dual-certification and guaranteed ±2 BTUaccuracy* combine to make these mixtures deliver unsurpassed performance when even a small error in measurement could have serious legal or commercial ramifications.

SCOTT Certified Class BTU mixtures are the most accurate and traceable gas and liquidmixtures available. They are gravimetrically prepared using our proprietary GRAVSTAT™

blending process. These standards are dual-certified and guaranteed to be traceable to anational or international metrology organization (usually NIST or VSL, formerly NMi) or toASTM, GPA, ALRS (Air Liquide Reference Standard) or other industry methods.

Benefits and Features ■ ±1% accuracy of components delivers guaranteed ±2 BTU accuracy* for consistently

accurate measurements.

■ Traceability to recognized standards provides unbiased third-party substantiation for absolute confidence in your measurements.

■ Dual-certification, independent blending and laboratory analytical values guarantee the accuracy of your mixture.

■ Exclusive interlocking concentration values provide an added measure of confidence in mixture accuracy.

■ Shorter lead times help minimize the need for on-site inventory.

* ±1 BTU accuracy is available on some products – contact your Air Liquide representative for more information.

Accurate Natural Gas Analysis

High quality analysis accepted by bothproducer and customer are characterizedby well-documented measurement, fully traceable to international standards.These international gas standards areprepared by several national metrologyinstitutes such as NIST (USA), LNE(France), BAM (Germany) and VSL(Netherlands). They intercompare theirgas standards frequently to guarantee international comparability. VSL is one ofthe leading laboratories and offers a fullrange of gaseous reference materials.

Air Liquide calibrates our measurementequipment with various metrologicalstandards. The foundation for accuracy and reliability is then established. Thesestandards for the natural gas industry arestable, gravimetrically prepared multi-component gas mixtures, of which theconstituent mole fractions and expandeduncertainty are listed in a Certificate ofComposition.

Exclusive Interlocking Concentration Values™

Certified Class BTU products receive two rigorous, independent methods of certification: one during GRAVSTATblending and the other using proprietarylaboratory analytical procedures. Air Liquide then further ensures the accuracy of your mixture by employingour exclusive interlocking feature: theconcentrations determined from bothcertification processes must interlock withagreement as low as 1%.

Natural Gas StandardsAir Liquide offers a comprehensive selection of natural gas and natural gas liquid (NGL)calibration standards. The mixtures below are available as SCOTT™ Custom Class™

products to meet your routine analytical requirements. Please contact your Air Liquiderepresentative regarding your specific applications.

Calorimetric This standard reflects the composition of many natural gas pipelines.

High Ethane Recommended for applications where heavier hydrocarbon values are notsignificant.

GPA The Gas Processors Association’s “GPA Standard of Analysis for Natural Gas andSimilar Gaseous Mixtures by Gas Chromatography” (GPA Publication 2261-72) and ASTM’sMethod D-1945-62T recommend this mixture for calibration and analysis.

Helium Enriched Natural gas containing a high level of helium requires a gas standardwith an appreciable increase in helium concentration.

Specific BTU Specific BTU methane is provided in high-pressure cylinders at 2000 psig(138 bar). Air Liquide makes standards for all BTU analyzers – please inquire.

Natural gas standards are commonly sold in size 108 cylinders (100 lbs.) or SCOTTY™ 14cylinders (volume dependent on mixture).

Natural Gas Cross Reference™

Analytical Service

To assure accuracy and precision in themeasurement of natural gas composition,BTU and specific gravity values, Air Liquideoffers a unique intercompany Cross Reference Service. Participating companiesreceive a sample of synthetic natural gas four times a year and return their gas analysis results to Air Liquide. A quarterly report is issued presenting individual results and summary data forall participants.

During plastic production, monomers polymerize to form long hydrocarbon chains througha continuous run. When a process upset occurs, the reaction must be stopped quickly toprevent the reactor from plugging with hardened plastics. For immediate termination ofthe reaction, kill gases are used. The chemical concentration of the kill gas depends on thepolymer formed. Common kill gases are shown in the table below.

FLAMAL, a stable, propylene-based high energy fuel gas, is a cutting-edgealternate to acetylene, propane, blended fuels and natural gas. When usedfor cutting, brazing, metalizing and heating applications, FLAMAL combinesthe best performance characteristics of acetylene with the safety of propane

to produce superior results.

Time, as they say, is money. Because of higher flame temperature and high BTU output inthe secondary combustion cone, when using FLAMAL, you can expect faster flame cutting,gouging, flame hardening and metalizing. In fact, it’s common to improve production by asmuch as 30% over propane or natural gas.

FLAMAL’s superior performance is a function of simple chemistry. It has a double bondbetween two of its carbon atoms which, when broken in the burning process, releases aprimary cone energy which is 94% of the energy released with acetylene. Compare this topropane or natural gas which has flame temperatures at least 700°F colder, with oxygenconsumption that is 20–30% higher than FLAMAL.

FLAMAL Vaporization

FLAMAL has the highest vaporization rate of all available fuel gases. This means you willexperience fewer fuel gas pressure problems in cold weather. Higher pressures and drawrates maintain production to such a high degree that many shops report they no longerneed vaporizers or manifolds when using FLAMAL.

FLAMAL is stable as a liquid and as a gas, and may be used safely at full cylinder pressures(i.e. 135 psi @ 70°F). FLAMAL has not been shown to detonate if a cylinder is dropped ordented. As with all flammable gases, proper safety precautions should be used at alltimes, observing all local, state and Federal guidelines. Contact your Air Liquide represen-tative for a FLAMAL cost savings analysis for your specific application.

PHARGALIS Gases■ Air

■ Carbon dioxide

■ Helium

■ Nitrogen

■ Oxygen

■ Numerous other specialty gasesAdditional Pure Gases Acetylene C2H2Acetylene is a standard fuel gas used in conjunction with oxygen for welding metals andcutting steel, and for allied oxy-acetylene processes for the heating, forming and treatingof metals. Acetylene is available in cylinders.

Air (Industrial Grade)Industrial grade compressed air is also available from Air Liquide. It is typically used to powerpneumatic tools and machines, inflate tires, clean assembly parts and for many other appli-cations. Industrial grade air is available in convenient single cylinders or multi-cylinder packs.

Argon ArArgon is an inert gas that is often used in shielded arc processes for welding aluminum,stainless steel, bronze and copper. In these processes, argon is used as a shielding gas,either in pure form or in combination with predetermined percentages of oxygen, carbondioxide or helium, depending on the metal being welded. The shielding gas provides an inertatmosphere during welding to prevent oxidation or other chemical change of the metalsthat would be detrimental to the weld. Argon is also used for inerting in other industriessuch as wine making and food applications, and is available in single cylinders or multi-cylinder packs.

RESPAL cylinders are equipped with our exclusive SCANDINA™ cap for addedsafety and a residual pressure valve to prevent backflow contamination of cylinder contents.

Additional Pure Gases continued

Carbon Dioxide CO2In addition to its well-known and extensive use as the carbonating and dispensing mediumin the beverage industry (see ALIGAL on page 252), carbon dioxide has numerous otheruses in many different industries. For example, in metal fabrication operations, CO2 is widelyused as a shielding gas in a semi-automatic welding process. In the food industry, CO2 isemployed for processing, packaging, transportation and refrigeration of meat products,frozen foods, dairy products and as an inert atmosphere over perishable products. CO2 iscommonly used to neutralize process and waste water streams. CO2 is available in singlecylinders or multi-cylinder packs.

Helium (Industrial Grade) HeHelium is used considerably in the welding industry as an inert shielding gas for arc weld-ing. It is used both as a pure gas and in mixtures with argon for TIG or MIG welding. Insome applications, helium has the advantage over argon in gas-shielded arc weldingbecause it provides greater arc heat for the same welding currents and arc length. Thisresults in deeper penetration which is preferable for welding heavier materials when greaterwelding speed is required or when metals of high thermal conductivity are to be welded.Helium is available in single cylinders or multi-cylinder packs.

Hydrogen H2As a fuel gas with oxygen, hydrogen produces a relatively low flame temperature of 5,125°F(2,830°C) and is most useful for the brazing of aluminum and magnesium, and for leadwelding. Because hydrogen can be safely compressed to overcome underwater pressures,oxy-hydrogen cutting torches are sometimes employed by divers on salvage operations.Mixed in small quantities with argon, hydrogen brings significant improvements in weldquality for stainless steels. It is also used in plastic brushing applications and for coolingin turbine power plant generators. Hydrogen is available in single cylinders and multi-cylinder packs.

Nitrogen N2Nitrogen is used in purging applications for heating, ventilation and plumbing industries.Large volumes of nitrogen are required by oil refineries and petrochemical industries forpurging and blanketing operations. Nitrogen is also being used at a sharply increasing rateby the food industry. In its liquid form, it is employed to quick-freeze a wide variety of per-ishable foods, some of which cannot be successfully frozen by conventional methods. Inits gaseous form, nitrogen is used in storage facilities for fresh produce to delay ripeningand deterioration. Nitrogen is available in single cylinder and multi-cylinder packs.

ISO/IEC 17025 Accreditation

SERVICES AND INDUSTRY OFFERINGSISO/IEC 17025 Accreditation, Solutions Center

Air Liquide Laboratories Provide Quality Assurance

ISO 17025:2005 is an internationally accepted laboratory Quality Management System(QMS) standard. Compatible with, but not equivalent to ISO 9001:2000, the accreditationis achieved through Accreditation Registrars such as A2LA or ACLASS, and is used toassess the technical competency of any laboratory that produces testing and calibrationresults. Management and technical components encompass laboratory activities including:sample preparation, analytical testing proficiency, measurement uncertainty, evidence oftraceability, document handling, records keeping and reporting.

ISO/IEC 17025:2005 specifies the general requirements regarding the competence toexecute tests and calibrations performed using standard methods, nonstandard meth-ods, and laboratory-developed methods. ISO/IEC 17025 provides laboratories aroundthe world the opportunity to establish and maintain a quality system designed to improveand validate their ability to consistently produce valid results. Compliance with regulatoryand safety requirements on the operation of laboratories is not covered by ISO/IEC17025:2005.

Commitment to Quality Versus Actual Value

Consider ISO/IEC 17025 accreditation as a third-party validation of a laboratory’s level ofproficiency and commitment to quality. Because this heightens a customer’s confidencein the specialty gases they purchase, in some industries, due to process specifications orother issues, use of 17025 products is mandatory. Few would argue that any measurethat increases quality can be anything less than beneficial regardless of application.

However, since most specialty gas suppliers maintain ISO/IEC 17025 certified laboratories,do not be misled into thinking the gases they produce are equal. First, accreditation is oftenproduct specific so it may apply to one particular product such as environmental mixtures,but not to other products. Second, while ISO/IEC 17025 seeks to establish a global levelof competency in the lab, it does not speak to many other factors that directly affect acompany’s ability to manufacture a broad line of well characterized and often uniqueproducts that provide better value when compared to similar products.

Shell Gas Correlation Scheme

Initiated by Shell Global Solutions withVSL (formerly NMi) and Scott SpecialtyGases (now part of Air Liquide), this proficiency testing program fills a gap in the existing correlation schemesavailable. It is operated by the DutchMetrology institute (VSL) in cooperationwith Air Liquide, with up to 20 participantsin LNG, natural gas, refining and chemi-cal processing industries.

Unknown mixtures are prepared, initiallyanalyzed and distributed by Air Liquide.Participants then analyze the blind samples and report their results, whichare evaluated and benchmarked by VSL. This international correlation schemeprovides an indispensable opportunityto assess and improve the analytical performance of a laboratory and is in linewith the validation requirements of theISO 17025 accreditation as a third linecontrol. Correlated samples can also bekept as a reference material/calibrationstandard with defined uncertainty.

SERVICES AND INDUSTRY OFFERINGSGlobal Cross Reference Services


Global Cross Reference™ ServicesTrue confirmation of accurate analytical results is best obtained by comparing analyticalresults among a number of independent, separate laboratories. Air Liquide facilitates thisconfirmation via our Global Cross Reference Service in which participating laboratories havea unique opportunity to assess the accuracy of their measurements through comparisonwith other labs in the global community. This process not only promotes a high degree ofconfidence in the accuracy of their analyses, but also helps identify potential problems in theaccuracy of those analyses.

How Our Cross Reference Services Work

1. Air Liquide creates identical unknown mixturesWe use our ACUBLEND™ or GRAVSTAT™ proprietary blending processes to produce a homogeneous batch of cylinders quarterly, then analyze them againstNIST-traceable standards. As a subscriber to our service, one of these cylinders is sent to you for analysis. For example, if you subscribe to our low level Nitric OxideService, you would receive a mixture whose concentration falls between 5 and 50ppm but would arrive at your door as an unknown.

2. Participants analyze the unknown mixture and report findings to Air Liquide using a Field Analysis Form that is supplied with the cylinder

3. Air Liquide reports analytical results to all participantsWe provide a report summarizing the analytical results for all participants (listed by code number or by the name of your organization, whichever you prefer). Report information includes mean and median concentrations, method of analysis, and statistical data such as variance mean, standard deviation and coefficient of variations.You retain the gas mixture for use as a high-confidence calibration gas standard.

Benefits of Participation ■ Improves credibility of your analytical laboratory capabilities.

■ Identifies potential analytical problems confidentially.

■ Provides inter and intracompany quality assurance.

■ Cross reference mixtures can be retained as high-confidence master calibration standards.

GAS HANDLING EQUIPMENTCylinder Connections


Cylinder ConnectionsFor nearly a century, the Compressed Gas Association (CGA) has been dedicated to thedevelopment and promotion of safety standards and safe practices in the industrial gasindustry. CGA fittings, which are used to attach to gas cylinders, are the gas industry stan-dard and are developed through the combined efforts of more than 200 member com-panies worldwide. Air Liquide offers CGA fittings for use with various gases.

Gas handling equipment that connects to your gas cylinder must have a compatible CGAfitting to mate with the gas cylinder valve outlet. For safety, it is important that you do notforce connections. Moreover, never use any pipe dope or Teflon® tape with CGA fittingswhen mating to the cylinder valve.

In general, these connections are designed for metal-to-metal sealing. CGA fittings come inbrass, chrome-plated and stainless steel, and in a variety of pressures and sizes. A sealingwasher is provided on those fittings that do not have a metal-to-metal seal. Adapters fromone CGA fitting to another should not be used to connect equipment to a high-pressurecylinder.

Air Liquide offers cylinder connections in a variety of configurations and materials. AllSCOTT™ regulators come equipped with a CGA fitting that matches its intended gasservice. Do not change the fitting on regulators. The CGA fitting is specific by gas type. AirLiquide recommends that regulators and sampling systems be dedicated to a specific gasservice, especially when the service is with an oxidant or corrosive gas. DISS connections(Diameter Index Safety Standard) are also available for electronic applications – see thefollowing page for all available connections. CGA and DISS illustrations are available, seepage 373.

GAS HANDLING EQUIPMENTPressure Regulators


Pressure Regulators Single vs. Two-Stage

Single-stage pressure regulators reduce cylinder pressure to delivery or outlet pressurein one step. Two-stage pressure regulators reduce cylinder pressure in two steps. Since the performance of each is influenced by mechanical characteristics, the choice of regulator depends on the requirements of the application.

The two most important variables to be considered are droop and supply pressure effect. Droop is the difference in delivery pressure between zero flow conditions and theregulator’s maximum flow capacity. Supply pressure effect is the variation in deliverypressure as supply pressure decreases while the cylinder empties.

Single-stage and two-stage regulators have different droop characteristics and responddifferently to changing supply pressure. The single-stage regulator shows little droopwith varying flowrates, but a relatively large supply pressure effect. Conversely, the two-stage regulator shows a considerable droop, but only small supply pressure effects.Generally, a single-stage regulator is recommended where inlet pressure does not varygreatly, or where periodic readjustment of delivery pressure does not present a problem. A two-stage regulator, however, provides constant delivery pressure with no need forperiodic readjustment.

Visit our website to view and purchase online from our huge selection of regulators, manifolds, flowmeters, cabinets and other gas handling equipment.

Performance Characteristics

Droop The change in delivery pressureas flow is initiated and increased throughthe regulator.

Supply and Pressure Effect The changein delivery pressure as the inlet pressurechanges. For most regulators, a decreasein inlet pressure causes the delivery pressure to increase.

Repeatability The change in deliverypressure after pressure has been set by turning gas flow on and off using anexternal valve.

Delivery Pressure Creep There are twotypes of creep. The first type is normal asa result of internal spring forces equalizingwhen the flow stops. The second type ofcreep is a result of contamination that,when left unchecked, can lead to regulatorand/or supply line failure.

Regulator Selection Materials

General Gas Use

General purpose regulators commonly have elastomeric diaphragms and are most often used in conjunction with packed valves. These regulators are typically forged brass but may be stainless steel depending on the corrosivity of the gas. Performance is satisfactory where slight contamination or diffusion from an elastomeric diaphragm is not important. Brass regulators with stainless steel diaphragms prevent air diffusionand adsorption of gases on the diaphragm. This is particularly important with low concentration mixtures of hydrocarbons where the trace component may be adsorbedon the elastomeric diaphragm. Regulators with Buna-N or neoprene diaphragms are notsuitable for GC analysis that can be affected by the diffusion of atmospheric oxygenthrough the elastomer diaphragm or the outgassing of monomers and dimers from the elastomer.

High-Purity Gas Service

Specialty gases can be effectively delivered by regulators that are classified as high-purityor ultra-high-purity. High-purity regulators are typically made of brass and have stainlesssteel diaphragms. Ultra-high-purity regulators are typically constructed of brass or stainless steel bar stock with convoluted stainless steel diaphragms having metal-to-metalsealing without using backup O-Rings. Ultra-high-purity regulators used with highlycorrosive gases typically have stainless steel diaphragms mechanically linked to thepoppet assembly to provide additional sealing integrity.

A high-purity regulator equipped with a stainless steel diaphragm does not outgas organic materials. It also prevents the diffusion of atmospheric oxygen into the carriergas whereas Buna-N and neoprene diaphragms are permeable to oxygen.

Operating Delivery Pressure Range

Determining the proper delivery pressure can be confusing. It is important to determinetwo application requirements: the gas pressure that is needed and the maximum pressure that the system may require (these two pressures may be the same). Then,select the regulator’s delivery pressure ranges so the desired pressures are between 5 and 90% of the regulator’s delivery range. A regulator’s performance is at its bestwithin this range.

Regulator Placement (Cylinder or Line)

Specialty gas regulator applications are divided into two types. The first is where the regulator is fastened to a gas cylinder using a Compressed Gas Association (CGA) fitting.The second application is where a regulator is located in a gas line, providing a meansto further reduce the line pressure. A line regulator is identified by having the inlet andoutlet opposite of each other with a single gauge in the 12 o’clock position to indicatethe reduced pressure.

Maintenance Schedule

Regulator maintenance is an importantpart of maximizing your system’s performance and extending the service life of your regulator. Adherence will minimize downtime and enhance safetyin your work area.

Service Noncorrosive or corrosive. See the Regulator Selection Guide tohelp you select the correct regulator foryour application.

Leak Check With the regulator underpressure, check all connections usingSnoop®. Shut down the gas source ifyou detect a leak, reduce atmosphericpressure and tighten or redo the connec-tion. If you are using toxic or corrosivegases, you must purge the connectionfirst with an inert gas. Then retest.

Creep Test Regulator creep is a phe-nomenon in which delivery pressure risesabove the setpoint and occurs two ways:1) changes to the motion of the regulatorsprings when gas flow is stopped, and 2) foreign material becomes lodged between the poppet and seat preventingtight shutoff.

Inert Purge In order to maintain cylinderintegrity and obtain optimum perform-ance, ALL regulators should be purged.For best results, utilize dilution purging –where alternating pressurizing and depressurizing the regulator with purgegas helps eliminate internal dead pocketsthat tend to hold contaminants.

Overhaul Remove all regulators fromservice periodically and return them to Air Liquide for inspection and overhaul.

Replacement Once the life expectancyof a regulator has been exceeded, itshould be replaced to protect against unexpected failure.

Contact Air Liquide for more informationon purging methods and regulator maintenance.

Liquid ChangeOver SystemsModel 8404L

SCOTT™ Liquid ChangeOver Systems are designed to provide a continuous supply of vaporized gas from two or more cryogenic liquid containers. It allows the user to depletegas in a container without the concerns of gas outages and wasting unused gas as aresult of premature changeouts. When in use, the built-in gas saver circuit directs accu-mulated pressure from the reserve supply container to the process before the containerrelief valve opens, venting useable product to the atmosphere. When the system is notoperating, the gas saver circuit inactivates allowing both containers to accumulate pres-sure and vent to atmosphere. Adequate ventilation should therefore be provided to safelyremove or dispense the gaseous discharge.

Benefits/FeaturesEliminates costly downtime by providing constant, uninterrupted gas flow.

Prevents gas outages and wasted gas due to premature dewar changeouts.

Reduces operating costs by permitting scheduled dewar changeouts.


Built-in gas saver circuit eliminates waste bypreventing the reserve supply’s accumulatedhead gas pressure from being discharged tothe atmosphere.

High-Purity Backup SystemsModel 8BGS and 8BDS

These systems are designed to provide automatic backup gas supply where gas generators, cryogenic dewars, compressors or house line gases are the primary sourceof process gas. They allow supply systems to be turned off for service or maintenancewithout disturbing the gas flow to high-purity applications. Unlike changeover systems,SCOTT™ backup systems automatically provide backup gas on an as needed basis,buffering deficiencies in supply pressure. The system activates (backs-up) when thesupply pressure drops below the preset pressure and deactivates when the supplypressure rises above the preset pressure allowing for the primary source of gas to flow.Monitoring or operator adjustments are not required during the backup activation ordeactivation.

The 8BGS system is provided with a low inlet primary pressure gauge for use with gasgenerators and low-pressure house lines. The 8BDS utilizes a higher inlet pressure gaugeto accommodate pressure readings from liquid dewars and compressors.

Benefits/FeaturesPrevents sudden and unexpected gas outages.

Improves operating efficiency by eliminatingdowntime.

Automatically switches between gas sourceswith no manual intervention necessary.

Compact design allows for easy wall mountingnear primary gas source.

Diaphragm-sealed valves allow for either supply pressure isolation or cylinder isolation when a change of cylinders is required.

Heating and Insulating Cylinder JacketsMix several hydrocarbon components in a cylinder, then expose that cylinder to lowtemperature. You’ll have a sticky situation. Heavier molecules drop out of the gas mixtureand stick to the cylinder walls, seriously compromising the accuracy of the mixture.

You can, however, prevent hydrocarbon and protocol mixtures from condensing. Our cylinder jackets feature a self-limiting heating cable that prevents overheating. As temperature increases, element resistance rises resulting in lower amperage to the heater. Lower amperage causes a wattage drop, thus limiting maximum attainabletemperatures. SCOTT™ cylinder jackets maintain cylinders temperature from 60°F (-18°C) to 120°F (49°C) depending on ambient temperature..

Benefits/FeaturesEliminates inaccurate calibration and processcontrol caused by temperature-compromisedgas mixtures.

Heats and insulates to prevent cylinder contentsfrom condensing.

Even distribution of heating cable prevents hotspots that can cause dangerous cylinder failure.

Velcro®/D-Ring closures ensure a snug fit.

Closed-cell foam insulation, with silicone-impregnated fiberglass liner and polyester exterior jacket, provide long-lasting weatherprotection.

Mass Flow ControllerModel 36A

Model 36A Series mass flow controllers utilize the specific heat properties of gases tomeasure true mass flowrate. In addition these mass flow controllers have an electro-magnetic control valve at the outlet which additionally gives them the ability to controlgas flows with a ±1% full-scale accuracy when coupled to our Model 36E Series secondary electronics (see page 327). Based on this control capability, they can alsobe used to perform gas blending operations.

Model 36A controllers are offered in ranges from 0.2 – 10 mL/min through 0.4 – 20 SLPM.They feature a 3-second response time with minimal overshoot and undershoot. In addition, these controllers are relatively attitude insensitive, allowing them to be installedin any mounting orientation with little effect on accuracy.

Flow Limit Safety Shutoff Valves Model 1

Model 1 Series flow limit safety shutoff valves automatically shutoff all flow from thecylinder when flow exceeds a factory preset level. The Model 1 is normally installed between the cylinder outlet and the inlet of the pressure regulator. It senses flow as apressure drop across the preset internal orifice; when the preset differential pressure limitis reached, the valve closes with a snap action for a leak-tight seal.

The quarter turn actuating knob is used to reset this device. Reset is required at startup,opening of the cylinder valve, during purging, and after correction of any process flowproblem or excess flow demand causing the Model 1 to shut off. The reset knob is designed to indicate clearly the operating position: Open (Reset) or Auto Shutoff.

Six flow ranges are available. The actual flow shutoff value for each range is dependentupon the operating pressure. The graph to the right shows the relationship between operating pressure and actual flow shutoff for each range. It is suggested that the rangeselected provides shutoff at six to ten times the anticipated actual process flowrate toallow for short term flow surges not connected with catastrophic line failure.

Model 1 Series flow limit valves range A through D have a 4 psi (0.3 bar) nominal operat-ing differential pressure. Ranges E and F have a 12 psi (0.8 bar) nominal operating differential pressure. The operating differential pressure is created by a small spring. This device is not affected by the mounting altitude. It works in any mounting positionindependent of gravity.

Indicating Pressure Switch GaugesModel 69M

These gauges are designed to provide pressure monitoring, setpoint indication and fastswitching for low power electrical signals. They are typically installed on regulators andmanifolds to activate an external alarm (such as an annunciator) when the predeterminedsetpoint pressure is reached. A magnetically actuated reed switch is capable of operatinglow voltage annunciators, lights or relays. The switch setpoint can be adjusted to anypressure between 2% and 90% of the full-scale value by moving the red indicator pin on the front of the dial to the desired setpoint. Model 69M gauges operate on decreasing pressure only where the magnetic indicating pointer opens the switch whencontact is made with the index. The gauges are designed to move further on the scalewhile permitting the switch to remain open after contact is made with the index.

Gas and Liquid Mixture Basics

TECHNICAL AND SAFETY DATAGas and Liquid Mixture Basics

Air Liquide’s product classes are designed to help our customers understand some of thescience behind the products they buy and to choose the right mixtures for their application.Our class descriptions use terms and definitions you may have heard before, however,specialty gas terminology can be confusing and the specialty gas industry does not useterminology consistently. The next few pages include an explanation of most of the keyterms found in our Gas and Liquid Typical Specifications Table on pages 86 and 87, andare intended to clarify your specialty mixture selection.

Concentration Ranges

In our Gas and Liquid Typical Specifications Table on pages 86 and 87, concentration rangesare shown in the first column. You will notice that the specifications for blend tolerance,analytical accuracy and process accuracy are dependent on concentration. The reason forthis is that gas mixtures become progressively more difficult to blend and analyze as theconcentration decreases, and hence, specifications must be relaxed accordingly. Saidanother way, a higher concentration results in a tighter blend tolerance, higher analyticalaccuracy, and higher process accuracy (i.e. smaller values), while a lower concentrationresults in a looser blend tolerance, lower analytical accuracy and lower process accuracy(i.e. larger values). Other factors affect specifications as well, including characteristics of theminor component, the type of balance gas or liquid used, instrument limitations, referencestandard accuracy, and the purity of the raw materials used to make the blend.

Component Verification

Component verification is the extent to which the concentrations of minor components ina mixture are checked for accuracy. For RATA, Compliance, Reference and ACUBLEND™

Master Class products, complete analysis is performed for all minor components in yourmix. This means that the concentration and accuracy of every component is independentlyanalyzed, using the appropriate instrumentation, reference standards and procedures. Forall dual-certified Reference Class products, and selected Certified Class products, concen-trations of minor components are measured gravimetrically and verified using GRAVSTAT™

process controls.

Blend Tolerance

Blend tolerance is important to assure that the mixture you order is at a concentration suit-able for your application and should not be confused with process accuracy. Blend toleranceis the difference between the certified concentration and the requested concentration fora given component. For example, if you order a mixture at a concentration of 100 ppm witha blend tolerance of 5%, then we must produce a product with a certified concentrationbetween 95 and 105 ppm (i.e. [100-95] / 100 = 0.05 or 5% relative) to be in specification.Blend tolerance will vary by the component and concentration you order, and will also bedependent on the manufacturing method used to make the blend. ACUBLEND MasterClass products offer the Zero Blend Tolerance option, meaning no difference between thecertified and requested concentration. For more information on Zero Blend Tolerance, referto page 93.

ACUBLEND Hits the Mark

SCOTT™ ACUBLEND products are recommended for applications requiringthe highest degree of consistency and repeatability from cylinder-to-cylinder.

Our unique Zero Blend Tolerance featuremakes it possible for us to meet your ordered concentration exactly, and to make as many cylinders as you needwith no variation in concentration.

We can provide a mixture to match anyexisting cylinder, regardless of its origin.Repeat orders can perfectly duplicateprior orders, and cylinders can be freelymixed and interchanged with no harmto your process. SCOTT ACUBLENDproducts offer you unparalleled perform-ance and speed of delivery, so yourmeasurements will always hit the mark.

Analytical Accuracy

Analytical accuracy is the difference between the analyzed concentration and the trueconcentration of a component. To make an analytical accuracy claim, the mixture youorder must undergo an independent laboratory analysis using an instrument, such as a gaschromatograph or FTIR, or using a chemical analysis method. In addition, the analysismust be calibrated with a reference material whose true value has been established, andthe key contributors to analysis variability must be quantified and controlled. This data canthen be used to calculate the analytical accuracy of the blend.

Analytical accuracy should not be confused with certified or certified accuracy. The termcertified is used in many different contexts in the specialty gas industry. Some vendorssupply certified mixtures and imply an analytical accuracy, when in fact no independentlaboratory analysis was done. It is important to understand how the manufacturer definesthe term certified before you purchase your next calibration standard.

Process Accuracy

Process accuracy is similar to, but not the same as, analytical accuracy – it is the differencebetween the blended concentration and the true concentration. To make a mixture with aprocess accuracy claim, the blending process used must have tight manufacturing controlsand must be calibrated with reference materials, such as NIST-certified weights, whose truevalue has been established. In addition, all the key contributors to process variability mustbe quantified and controlled, so that the accuracy can be calculated. A gravimetric scale,in many respects, is similar to an analytical instrument. The device is highly sensitive, canbe calibrated, and can be used to measure both the concentration and the accuracy of acomponent. A properly controlled process, such as GRAVSTAT™, can yield tight accuracyspecifications, sometimes even tighter accuracy specifications than analytical accuracy,and is an example of a manufacturing technique for which a process accuracy can becalculated.

Reproducibility

Our reproducibility specification was developed exclusively in response to our customers’demand for cylinder-to-cylinder comparability. This number specifies how well the concen-tration of your current cylinder will agree with that of your replacement cylinder, whencompared on your instrument. Reproducibility is not a value that is measured directly, butit is a necessary result of the analytical accuracy and/or process accuracy. Air Liquide isable to guarantee reproducibility because our accuracy specifications measure how wellwe have determined the true value of your mix.

The benefit of the reproducibility specification becomes apparent in an application oper-ating under statistical process control (SPC). Use of a replacement calibration standard,if significantly different in concentration from the current standard, could necessitate a changein SPC calibration and control parameters, causing a process upset. The reproducibilityspecification available exclusively from Air Liquide can save you time and money by avoid-ing these potentially costly incidents.

Traceability

Traceability is important as companies adopt quality certifications. Laboratories, for ex-ample, must establish traceability of measurements to earn ISO/IEC 17025 accreditation.Traceability is the pathway or linkage back to the true value of a measurement. For trace-ability to exist, there must be an unbroken chain of comparisons between the measuredvalue and an accepted reference that is recognized in the national or international measure-ment system. In specialty gases, there are two types of traceability, analytical traceabilityand process traceability. Analytical traceability can be achieved through use of gas referencematerial, such as a NIST SRM, while process traceability can be achieved by measurementof a fundamental physical parameter, such as mass, temperature or pressure.

Analytical Traceability

Analytical traceability is the link between the analyzed concentration and the true concen-tration for a gas mixture. Analytical traceability is achieved by laboratory analysis of yourmixture on an instrument directly calibrated with gas reference material from a recognizedmetrology organization such as NIST, VSL or NPL. For example, when the analysis isperformed with a NIST SRM or NTRM, the resulting product is said to be “directly NIST-traceable.” For specialized applications, traceability can also be linked to consensus stan-dards created by trade or industry groups, where no national or international referencestandards are available. Examples include reformulated gasoline calibration standards formeasurement of oxygenate and sulfur levels in gasoline.

The high cost of reference standards like SRMs makes it economical for gas suppliers toblend intermediate standards – so-called Gas Manufacturers Intermediate Standards(GMISs) – and analyze them against SRMs. The unbroken chain of traceability can still bemaintained even if GMIS-type standards are used, however, the accuracy of this labora-tory analysis will be lower. Every step that intervenes between the product analysis and theoriginal reference standard results in more uncertainty for the mixture you buy. In addition,the resulting products will be traceable, but not directly traceable. If your application requiresdirect traceability like many environmental measurements, be sure your gas supplier hasaccess to and uses the correct reference standard.

Process Traceability

Process traceability is very similar to analytical traceability – it is the link between the blendedconcentration and the true concentration for a gas mixture. In order to have process trace-ability, the blending method used for your mixture must also be directly calibrated withreference material from a recognized metrology organization such as NIST, VSL or NPL.For example, if a gravimetric blending scale is calibrated with NIST Class 1 weights, or theolder Class S weights, the resulting product is said to be NIST-traceable by weight. Processtraceability is extremely important for product classes, because traceability for this single-certified product can only be achieved through weight-traceability. Air Liquide is the onlyspecialty gas company that guarantees traceability for all product classes.

Critical Impurities Analysis

Every specialty gas mixture contains at least one minor component for which the certifiedconcentration and accuracy are needed. But in some applications, the presence of othertrace impurities in the mixture can interfere with the proper functioning of analytical equip-ment and could result in poor quality analytical results. For example, one application mayrequire a mixture of 500 ppm of carbon monoxide in nitrogen, with dual-certification,±1% accuracy and direct NIST-traceability, but trace sulfurs must be below 1 ppm to avoidcontamination or interference. In this case, the trace sulfurs constitute the critical impurities.In this instance we would check the quality of all raw materials for trace sulfurs, and thenanalyze the final blend to assure that your trace sulfur impurity specification was met.

Trace level impurities can originate from the raw materials used, the balance gas/liquid usedor from the blending process. Air Liquide’s manufacturing processes track and keep traceimpurities to a minimum, and offers the analysis of critical impurities as an option for Ref-erence and Custom Class™ mixtures.

Minor Components

Air Liquide offers the industry's widest range of components for manufacture of gas andliquid mixtures. Components such as atmospherics, hydrocarbons, inert gases and evenreactive components such as nitric oxide, hydrogen sulfide and 1,3-butadiene are available.Our standard components list is shown on pages 14 and 15, but this is only a partial listof the components Air Liquide will blend. In Custom Class, Air Liquide will also makeblends of components you specify that can include rare or unusual materials. In addition,Air Liquide will manufacture mixtures using raw materials that you supply.

Reactive Components

Mixture components can be classified into two main types – reactive and inert (nonreactive).A reactive component is one that exhibits erratic behavior, most commonly observed asinstability – a significant drop in the expected concentration when blended into mixtures.There are several ways that a component can earn a reactive designation. Some com-pounds react with other components of the mixture or with the balance material, andthese reactions can be accelerated in a high-pressure cylinder. Other components are“sticky,” that is, they attach themselves to the cylinder wall or delivery system and dropout of the mixture. Both of these conditions lead to unstable mixtures. Air Liquide’s pro-prietary blending techniques minimize or compensate for component reactivity. See page84 for more information.

Reference Standard Accuracy

Virtually all instrumental methods of analysis require use of a reference standard to make anaccurate measurement. For all laboratory analyzed products, Air Liquide uses referencestandards that are equal to or more stringent than the required analytical accuracy spec-ifications. For EPA protocol mixtures, Air Liquide uses only SRMs, NTRMs, PRMs and EPAGMISs as reference standards. For Reference, ACUBLEND™, Custom and selectedCertified Class mixtures, we use Air Liquide Reference Standards (ALRSs), or accuratelyprepared temporary standards as reference standards, all of which meet Air Liquide’sstringent accuracy specifications. These are the best reference standards available in theindustry, short of a NIST or VSL certified standard.

Certificate of Accuracy

Air Liquide provides a detailed Certificateof Accuracy for every product class. The Certificate of Accuracy reports the official concentration for every com-ponent, as well as other important datademonstrating that the mixture meetsour class specifications.

In Custom Class, Air Liquide offers theopportunity to design or specify a Certificate of Accuracy matched to exactneeds. An example Certificate of Accu-racy is shown for several product classeson pages 88 to 98. The Certificate of Accuracy is your assurance that themixture you bought meets Air Liquidespecifications and your requirements.

Standard Industry Methods

The legacy of Scott Specialty Gases is well-known for its ability to analyze gas mixtures withhigh precision and accuracy. For all laboratory analyzed products, Air Liquide uses SCOTT™

developed analytical procedures to achieve the concentration and accuracy specifications.But for some applications, customers require certification of their mixture by a specificanalytical procedure. For instance, refinery customers measuring sulfur emissions oftenrequire analysis of H2S by EPA Method 11, the EPA’s approved reference method.

SCOTT RATA Class™ and Compliance Class™ mixtures are certified using standard EPAprotocol procedures required to produce a compliant product. For Reference and CustomClass™, Air Liquide also offers further analysis of mixtures using industry standard methodsas specified or requested by the customer. These additional analyses add value by makingyour mixture from Air Liquide perfectly matched to your application.

Physical Property Notifications

The physical properties of components used to make specialty gas mixtures vary greatly.A common limitation in preparing mixtures is that one or more components has a low vaporpressure at room temperature. Such mixtures can frequently be prepared by reducing thetotal pressure of the mixture to avoid possible condensation of the less volatile components.When this situation occurs, Air Liquide alerts you by printing actual mixture properties (i.e.dew point temperature, vapor pressure restrictions) on the label and Certificate of Accuracy.For applications where mixture pressure and dew point are critical, a full mixture phaseenvelope can be provided for Reference, ACUBLEND™ and Custom Class mixtures.

Raw Material Quality Control

Air Liquide has long recognized that controlling impurities in raw materials is critical for pro-ducing highly accurate specialty gas mixtures. Our raw materials are carefully selected andtested for trace impurities prior to use. For our gravimetric products, we go one step further.For Reference Class, raw materials are analyzed and certified not just for trace impurityconcentrations, but also for the accuracy of raw material purity. The accuracy is a criticalelement of achieving our process accuracy specifications.

Product Shelf Life

Product shelf life is the length of time over which Air Liquide will guarantee that componentsof a gas mixture remain at their certified concentrations within the specified tolerances. Ourshelf life claims are based on formal stability studies, and on more than 50 years of historyand experience blending specialty gas mixtures. Some mixtures also have an expirationdate that is usually set by regulations (i.e. EPA protocols) and is always shorter than thelength of time that the mixture is actually stable. Air Liquide employs ACULIFE™ and otherproprietary cylinder treatment processes to guarantee mixture shelf life and stability.

Air Liquide uses extensive laboratorycontrol procedures to analyze all raw

materials for impurity levels.

TECHNICAL AND SAFETY DATACompressed Gas Definitions


All cylinders containing Air Liquide gases are labeled, packaged and shipped according to local and national requirements, as well as industry standards. Transportation label diamonds, regardless of color, indicate hazardous materials. Personnel handling any com-pressed gas should be familiar with the potential hazards before using the gas. In additionto the chemical hazards of compressed gases, hazards accompanying high pressure or low temperature may also be present due to the physical state of the gas (i.e. liquefied or nonliquefied).

We also recommend that personnel who handle compressed gases engage in prejobdiscussion with their supervisor or another knowledgeable coworker before beginningany task. Outline the job step by step, as well as any actions necessary to complete thejob. Address potential emergencies, and the safe and proper measures necessary toavoid these emergencies. Identify several scenarios that could result in gas leaks or otheremergencies to be fully prepared to respond adequately. If there is doubt regardingproper safety procedures, consult your Air Liquide representative. Further informationconcerning the safe handling, storage and use of compressed gases, in addition to theinformation presented in this catalog, is available from Air Liquide.

Compressed GasAny nonflammable material or mixture having a pressure exceeding 41 psia (3 bar) at 70°F(21°C) in the container, or any flammable or poisonous material that is a gas at 70°F (21°C)and has a pressure of 14.7 psia (3 bar) or greater. Most compressed gases will not exceed2,000 to 2,640 psig (138 to 182 bar), though some will go up to 6,000 psig (414 bar).

Nonliquefied Compressed GasA chemical or material other than gas in solution that, under the charged pressure, is entirelygaseous at a temperature of 70°F (21°C).

FLAMMABLE GAS

Asphyxiant GasesThese are gases that are non- or minimally toxic but which dilute the oxygen in air leadingto death by asphyxiation if breathed long enough. Toxic gases in large enough concentra-tions can also cause asphyxiation and lead to death by other mechanisms such as in-teraction with the respiratory system by competing with oxygen (such as carbon monoxide)or causing direct damage (such as phosgene). Because asphyxiant gases are relativelyinert, their presence in large quantities may not be noticed until the effects of elevatedblood carbon dioxide are recognized by the body. Notable examples of asphyxiant gasesare nitrogen, argon and helium.

Corrosive GasesThese are gases that corrode material or tissue with which they come in contact, or doso in the presence of water. They are reactive and can also be toxic and/or flammable or anoxidizer. Most are hazardous in low concentrations over long periods of time. It is essentialthat equipment used for handling corrosive gases be constructed of proper materials. Usecheck valves and traps in a system where there is a possibility that water or other inorganicmaterials can be sucked back into the cylinder. Due to the probability of irritation anddamage to the lungs, mucous membranes and eye tissues from contact, the threshold limit values of the gas should be rigidly observed. Proper protective clothing and equipmentmust be used to minimize exposure to corrosive materials. A full body shower and eye washstation should be in the area.

Cryogenic GasesThese are gases with a boiling point of -130°F (-90°C) at atmospheric pressure. They areextremely cold and can produce intense burns. They can be nonflammable, flammable oroxidizing. Cryogenic liquids can build up intense pressures. At cryogenic temperatures,system components can become brittle and crack. Never block a line filled with cryogenicliquid, as a slight increase in temperature can cause tremendous and dangerous buildupof pressure and cause the line to burst. The system should also be designed with a safetyrelief valve and, depending upon the gas, a vent line. Always wear gauntlet gloves to coverhands and arms, and a cryogenic apron to protect the front of the body. Wear pants overthe shoes to prevent liquids from getting trapped inside your shoes. Wear safety glassesand a face shield as cryogenic liquids tend to bounce up when they are spilled.

Flammable GasesThese are gases that, when mixed with air at atmospheric temperature and pressure, forma flammable mixture at 13% or less by volume, or have a flammable range in air of greaterthan 12% by volume regardless of the lower flammable limit. A change in temperature,pressure or oxidant concentration may vary the flammable range considerably. All possiblesources of ignition must be eliminated. Use a vent line made of stainless steel, purge withan inert gas and use a flash arrester. It is important to have a fire extinguisher where flam-mable gases are used and stored. A hand-held gas detector is also recommended to guardagainst gas buildup and to detect leaks in gas lines. Remember that the source of gas mustbe eliminated before attempting to put out a fire involving flammable gases.

Inert GasesThese are gases that do not react with other materials at ordinary temperature and pressure.They are colorless and odorless, as well as nonflammable and nontoxic. Inert gases candisplace the amount of oxygen necessary to support life when released in a confined place.Use of adequate ventilation and monitoring of the oxygen content in confined places willminimize the danger of asphyxiation.

Oxidant GasesThese are gases that do not burn but will support combustion and they can displace oxygenin air (with the exception of O2 itself). It is essential that all possible sources of ignition beeliminated when handling oxygen and other oxidants as they react rapidly and violently. Do not store combustible materials with oxidants. Do not allow oil, grease or other readilycombustible materials to come in contact with a cylinder or equipment used for oxidantservices. Use only equipment that is intended for this type of service. Use only a regulatorthat is designated and labeled “cleaned for O2 service.”

Pyrophoric GasesGases such as silane, phosphine, diborane and arsine are commonly used in the semi-conductor industry and are extremely dangerous to handle because they do not require asource of ignition to explode or catch fire. Pyrophoric gases will ignite spontaneously inair at or below 130°F (54°C). Specific gases may not ignite in all circumstances or mayexplosively decompose. Under certain conditions, some gases can undergo polymerizationwith release of large amounts of energy in the form of heat.

Toxic or Poison GasesThese are gases that may chemically produce lethal or other health effects. They can behigh-pressure, reactive, flammable or nonflammable, and/or oxidizing in addition to theirtoxicity. The degree of toxicity and the effects will vary depending on the gas. Permissibleexposure levels must be strictly adhered to (please refer to the PELs listed in this catalog).Read the MSDS thoroughly before use. Never work alone with toxic gases—inspect thesystem that will contain the gas and thoroughly test it for leaks with an inert gas before use.Purge all lines with an inert gas before opening the cylinder valve or breaking connections.

Use toxic gases in a well-ventilated area. It is important to have gas detectors, self-containedbreathing apparatus and protective clothing on hand. The breathing apparatus must bestored in a safe area immediately adjacent to the work area, so that in the event of anemergency, a person can go directly into the area and close the door and safely put on theapparatus. Full body showers, eye washes, fire alarms and firefighting equipment shouldbe readily accessible.

Refer to your local building code for storage and use requirements for toxic gases. Keepyour inventory of toxic or poison gases at a minimum. When a project is completed, returnleftover cylinders to Air Liquide. They should never be stored for possible future use. Thismight result in accidental removal of cylinder labeling, making it an unnecessary hazard andgreatly increasing the cost of proper disposal.

Gas Compatibility

TECHNICAL AND SAFETY DATAGas Compatibility

The compatibility data shown on the following pages has been compiled to assist inevaluating the appropriate materials to use in handling various gases. Prepared for use withdry (anhydrous) gases at a normal operating temperature of 70°F (21°C), information mayvary if different operating conditions exist.

It is extremely important that all gas control equipment be compatible with the gas beingpassed through it. The use of a device that is not compatible with the service gas maydamage the unit and cause a leak that could result in property damage or personal injury.To eliminate potentially dangerous situations, always check for compatibility of materials before using any gases in your gas control equipment. Systems and equipment used inoxidizer gas service (i.e. oxygen or nitrous oxide) must be cleaned for oxidizer service.Since combinations of gases are unlimited, mixtures (except for ethylene oxide/halocarbonand ethylene oxide/CO2 sterilizing gas mixtures) are not listed in this Compat ibility Chart.Before using a gas mixture or any gas not listed in the chart, please contact your Air Liquiderepresentative for more information.

Locate the gas you are using in the first column.

Compare the materials of construction for the equipment you intend to use with the materials of construction shown in the Compatibility Chart. Use the Key to Materials Compatibility to determine compatibility.

TECHNICAL AND SAFETY DATASpecial Precautions

Emergency Responsein US: 800.324.7814in Canada: 514.878.1667Describe the nature of your problem and gases involved. We will have one ofour emergency response coordinatorscontact you with information on how tosafely handle the situation.

Transportation of Cylinders

Specialty gas cylinders should never betransported in passenger vehicles. Whilecertain flammable gases like acetyleneand propane may be transported in openbed pickup trucks, other flammablegases and toxic gases are not allowed inthis type of vehicle. Cylinders must beadequately secured and vehicles mustbe properly placarded for the gases theytransport.

Customers may be able to safely trans-port limited quantities of particular gases,but the preferred method of transportingcylinders of compressed gas is to haveAir Liquide deliver and pick up the cylinders by truck or tractor-trailer with a permanently separated cab. Contactyour Air Liquide representative for moreinformation.

Additional Information

For further technical and safety informationabout specialty and liquefied gases, referto individual Material Safety Data Sheets(MSDSs), the Air Liquide Gas Encyclopaedia,or the Air Liquide video “Hazards of Liquefied and Compressed Gases.” Information can also be found in publicationsand videos produced by the CompressedGas Association at the following location:

4221 Walney Road Suite 500Chantilly, VA 20151-2923 (703) 788-2700www.cganet.com

Air Liquide urges our customers to include safety information on compressed and liquefiedgases in their safety training programs. The following, as well as additional literature andother training aids, are available for inclusion in your training programs. On-site safety auditsby our trained personnel can also be arranged for your convenience – contact your AirLiquide representative for more information.

Always use recommended protective equipment when using specialty gases

Appropriate personal protective equipment such as respirators, eye protective equipment,chemical resistant gloves and clothing should be worn when using certain products. Related safety equipment such as eye wash stations and showers should be nearby andinspected frequently to make certain that they function properly. Ambient air monitors thatdetect specific gases are important safety devices recommended for many gases, partic-ularly those gases which can be lethal in low dosages.

Always know what to do in case of fire or emergency situation

Before working with flammable, oxidizing or toxic gases, read the safety information con-tained in the MSDS that ships with cylinder and is available online. Develop a plan for actions to take in the event of a leak or fire and make certain that emergency equipmentis available. If a fire should occur, try to stop the flow from the gas source if possible. Oth-erwise, when the fire is extinguished, gas may accumulate creating an explosive hazard.Make sure that enclosed spaces where gas can build up are well vented and the gas isdissipated before entering the area.

Cylinder fires can be especially dangerous since multiple cylinders may be stored in thesame area. If a cylinder should start to burn, the resulting heat may cause surroundingcylinders to rupture and fuel the fire. Cool neighboring cylinders with water spray andeliminate other possible sources of ignition if possible.

Leaking cylinders can present their own unique hazards. Small leaks around valve outletsmay be stopped easily by tightening the fitting. Make sure workers wear the appropriateprotective equipment before trying to stop even the smallest leak of hazardous gases. Neverattempt to repair a leak where the valve threads into the cylinder or the safety. For largerleaks or leaks that cannot be stopped, evacuate area personnel who may be exposed.

Gas Disposal

Disposal of waste gas can present the same problems as a leaking cylinder. Normally,waste gases can be vented out of the work area and into appropriate disposal systems.Consult with your Air Liquide representative for information on proper methods of disposalof hazardous gases. Also, if certain gases are mixed, their properties may change to createadditional hazards. This can happen if several different gases are vented into one commonexhaust system. Separate vent lines may be necessary particularly for reactive gases. Unused gas contained in cylinders should be returned to Air Liquide.

TECHNICAL AND SAFETY DATACylinder Storage, Handling and Usage


Federal, state or local fire codes may restrict the storage and handling of certaingases. One recommended method of handling such gases is the use of appropriately designed gas cabinets.

These fully enclosed units, such as theSCOTT™ Model 9 Gas Safety Cabinet,will hold from one to four cylinders andmay have such features as exhaust ventilation, fire suppression systems and alarms. These cabinets can be fullyautomated or operated manually with little or no potential exposure to personnel.

Cylinder Storage, Handling and UsageStorage

General Storage Appropriate firefighting, personnel safety and first aid equipment shouldbe available in case of emergencies. Ensure adequate personnel are trained in the use ofthis equipment. Follow all federal, state and local regulations concerning the storage ofcompressed gas cylinders. Refer to the Compressed Gas Association (CGA) pamphlet P-1for further information.

Storage Area Store gas cylinders in a ventilated and well-lit area away from combustiblematerials. Separate gases by type and store in assigned locations that can be readilyidentified. Store cylinders containing flammable gases separated from oxidizer cylindersand other oxidants by a fire-resistant barrier with a minimum height of 5' and (having afire-resistance rating of at least a half hour) or locate them at least 20 feet (6 meters) apartfrom each other. Poison, cryogenic and inert gases should be stored separately. Labels,decals or other cylinder content identification should not be altered or removed from thegas cylinder. Cylinders should also be stored where they can be protected from tam-pering by unauthorized personnel.

Storage Area Conditions Storage areas should be located away from sources of excessheat, open flame or ignition, and not located in closed or subsurface areas. The area shouldbe dry, cool and well ventilated. A hood is not a safe storage area except for when thecylinder is actually in use. Outdoor storage should be above grade, dry and protected fromthe extremes of weather.

Securing Cylinders in Storage The risk of a cylinder falling over and possibly shearingoff its valve demands that a cylinder always be held in place with a chain or another type of fastener such as bench or wall clamp. While in storage, cylinder valve or SCANDINA™

protection caps MUST be firmly in place.

Cylinder Temperature Exposure Cylinder temperature should not be permitted to exceed125°F (52°C). Steel cylinders are more durable than aluminum cylinders. They are designedfor high-pressure and more corrosive products. They should not be stored near steampipelines or exposed to direct sunlight. Aluminum cylinders are used for increased stabilityof mixtures containing certain components. They can be damaged from exposure totemperatures in excess of 350°F (177°C). These extremes weaken the metal walls and thecylinders begin to lose their strength. Do not apply any heating device that will heat any partof the cylinder above 125°F (52°C). Over heating can cause the cylinder to rupture.

Storing Empty Cylinders Arrange the cylinder storage area so that old stock is used first.Empty cylinders should be stored separately and identified with clear markings. Returnempty cylinders promptly. Some pressure should be left in a depleted cylinder to preventair suck-back that would allow moisture and contaminants to enter the cylinder.


Handling

General Handling Safety glasses, gloves and safety shoes should be worn at all timeswhen handling cylinders. Appropriate firefighting, personnel safety and first aid equipmentshould be available in case of emergencies.

Transporting Cylinders Always move cylinders by a hand truck or cart designed for thispurpose. During transportation, cylinders should be properly secured to prevent them fromfalling, dropping or striking each other. Never use a cylinder cart without a chain. Do notmove a cylinder with a regulator connected to it. Never transport a gas cylinder without itsvalve protection cap firmly in place. Keep both hands on the cylinder cart during transport.Remember a cylinder cart or hand truck is not a suitable place for storage of a cylinder. If a cylinder is equipped with a SCANDINA™ cap, do not remove it. Never lift a cylinderby its cylinder cap. The threads are affixed to the cylinder body; lifting it by the cap will causethe cap to detach from the body.

Usage

General Usage Appropriate firefighting, personnel safety and first aid equipment shouldbe available in case of emergencies.

Labeling If a cylinder’s contents are not clearly identified by the proper cylinder labels, doNOT accept for use. Observe all warnings and precautions indicated on the cylinder label.

Securing Cylinders Before Use When a cylinder is in use, it must be secured with a fastener. Floor or wall brackets are ideal for stationary use. Portable bench brackets are recommended for when cylinders must be moved. Smaller stands are available as well forlecture bottle use. Your Air Liquide representative can assist you in determining which typeof cylinder fastener best meets your needs.

Initiating Service of Cylinder Secure the cylinder before removing the valve protectioncap. Remove the protective cap and inspect the cylinder valve for damaged threads, dirt,oil or grease. Do not remove a SCANDINA cap. Remove any dust or dirt with a clean cloth.If oil or grease is present on the valve of a cylinder that contains oxygen or another oxidant,do NOT attempt to use it. Such substances in contact with an oxidant are explosive. NotifyAir Liquide of this condition.

Valve Outlet Connections and Fittings Be sure fittings and connection threads meetproperly – never force. Dedicate your regulator to a single valve connection even if it isdesigned for different gases. NEVER cross thread or use adapters between nonmatingequipment and cylinders. Most valve outlet connections are designed with metal-to-metalseals; use washers only if indicated. Do not use Teflon® tape on the valve threads to preventleaking, it may become powdered and get caught on the regulator poppet causing fullpressure downstream. Never use pipe dope on pipe threads. Also, never turn the threadsthe wrong way. This may produce brass particles that might get caught in the regulator’spoppet.

Terminating Service of Cylinder Always disconnect equipment from the cylinder whennot in use and return the valve protection cap to the cylinder.

Safety SeminarsAir Liquide offers its customers Gas Handling Safety Seminars focusing onsafety considerations in the use of compressed gases as well as periodicwebinars. These seminars are conductedat your facility by trained Air Liquide representatives.

The first portion of the session concernscompressed gas classifications and theirassociated safety requirements in regardto storage, transportation and use. Thesecond part of the presentation involveshands-on demonstration of cylinder handling equipment, valves, pressure regulators, purge devices, leak-checkingequipment and other state-of-the-artsafety equipment. DOT and OSHA labelingand Material Safety Data Sheets are alsodiscussed. Air Liquide representativesanswer questions and address specificareas of interest at the end of the seminar.

Safety Video for CompressedCylinder Gases

Safe Handling of Compressed CylinderGases is a comprehensive 42-minutevideo detailing potential hazards in thelaboratory and in manufacturing facilities.This DVD depicts the safe handling andproper storage of inert, flammable, oxidizing,corrosive, poisonous and cryogenic gasesin cylinders. It is an excellent addition to anysafety program.

E. Electronic and Poisonous GasesFor semiconductor or poisonous labeledcylinders, contact the Air Liquide ShippingManager at the facility nearest your locationfor details on proper shipping procedures.

F. SCOTTY™ Cylinders(Nonreturnable and Lecture Bottles)Air Liquide does not accept the return ofthese types of cylinders.

Preparing for Shipment

Before returning, check your cylinders for thefollowing:

A. Be sure CGA outlet dust caps (if supplied)are in place before securely screwing valvecaps onto top of cylinders. Please note thatall cylinder caps are not interchangeable. Youare responsible for the care and condition ofrefillable and returnable cylinders while atyour facility, as well as damage to the cylin-ders themselves, cylinder caps and fittingsthat occur while in your care.

B. All labeling or markings on the cylindersmust be legible. The shoulder labels on thecylinder provided by Air Liquide should NOTbe removed from the cylinder as they iden-tify the cylinder gas contents.

C. All cylinders should be returned with atleast 50 psig (3 bar) positive pressure toavoid contamination of the cylinder. Ensurethe valve is closed during shipping.

D. It is important to treat empty cylinders thesame as you would if they were full and useall precautionary measures practiced whenhandling full cylinders.

Preparing the Documentation

A bill of lading needs to be prepared for thecylinders being returned. Contact your AirLiquide representative for a sample. The following is required by the U.S. DOT or theshipping authority in your country.

A. Quantity of Cylinders ShippedList cylinders of gas mixtures separately if thecomponents are different.

B. Type of ContainerPlace “CYL” below your quantity amount.

C. Hazardous MaterialCheck off the Hazardous Material columnwith an “X.” All Air Liquide gases are con-sidered hazardous materials.

D. Description of ContentsFor gas mixtures, begin your description withlast contained, followed by compressed gas,n.o.s. and hazard class or division. For propershipping names ending in n.o.s., a minimumof the two most hazardous chemicals mustbe listed. List the cylinder contents, startingwith the concentration range first (i.e. 500ppm SO2, 5% CO2, balance N2). For puregases, the proper shipping name is usuallythe gas name.

E. An Accurate UN NumberAll cylinders require a UN number whenbeing shipped (placed on the cylinder by AirLiquide). If you cannot locate this number onthe cylinder, please contact your Air Liquiderepresen tative to assist in determining thecorrect UN number.

F. WeightSee pages 1 to 8 for specifications and sizesof cylinders offered by Air Liquide.

Glossary

GLOSSARYTerms and Definitions

AAAbbreviation commonly used for Atomic Adsorption spectroscopy.

Absolute PressureA measurement of pressure which sets a totalvacuum as having a value of zero, abbreviatedas psia or bar. Absolute pressure is equal to thesum of a pressure gauge reading and atmosphericpressure (14.69 psia or 1 bar at sea level).

Absolute ZeroThe minimum point on the thermodynamic temperature scale: 0°K, -459.69°F or -273.16°C.

AccuracyThe degree of statistical agreement (usually atthe 95% confidence level) between a measuredvalue and the true value, or the certainty or sure-ness with which a measured value is known.

ALPHAGAZ™

A registered trademark for pure and instrumenta-tion specialty gas products offered by Air Liquideworldwide.

American Conference of GovernmentIndustrial Hygienists (ACGIH)A group that makes recommendations on the exposure levels of hazardous materials in the workplace.

American Society of Testing Materials (ASTM)An organization that sponsors committees thatdevelop standards for industrial manufacturersand consumers.

AnaerobicGases that do not contain oxygen and are usedfor biological culture growth.

AnalysisInstrumental analysis in the lab after blending; a process based on statistics used to estimatethe true concentration for each component of a gas mixture and to assign the analyzed con-centration. A further objective of analysis is to determine the analysis accuracy for eachcomponent. Analytical measurements have sufficient work content to assure that componentconcentrations and accuracies meet customerand Air Liquide specifications.

Example: A Certificate of Accuracy statingComponent X: 100 ppm ±2% (mole/mole)means Air Liquide has analyzed this gas mixtureand determined that the most probable valuefor Component X is 100 ppm and the true value is between 98 and 102 ppm, on a mole basis,at the 95% confidence level.

Analytical AccuracyThe difference or degree of statistical agreementbetween the analyzed and the true concentrationfor a component of a gas mixture (usually at the95% confidence level), or the certainty or surenesswith which the analyzed concentration is known.Analytical measurements have sufficient anchoring to reference standards, calibration,precision, resolution and traceability to assurethat the true concentration for a componentcan be estimated to the claimed accuracy. Analytical accuracy can be calculated becauseAir Liquide analytical measurements require actual data for reference standards, calibration,precision, resolution and traceability.

Analytical ToleranceThe degree of agreement between the analyzed concentration and the requested concentration for a component. Analytical tolerance is not determined by statistical means (whereas analytical accuracy is).

Analyzed ConcentrationThe numerical concentration assigned to acomponent based on the results of analysis.The analyzed concentration is expressed inboth concentration units (i.e. percent, parts permillion) and concentration basis (i.e. mole/mole,weight/weight). An analyzed concentration isalso accompanied by an analysis accuracyvalue (i.e. ±2%).

AnhydrousA term meaning without water or dry. It is oftenused with gases that are particularly corrosive inthe presence of moisture such as ammonia.

Asphyxiant GasA gas that displaces air in an enclosed spaceand can render unconsciousness or death dueto a lack of oxygen.

Avogadro's LawA gas law that states that equal volumes ofgases at the same temperature and pressurecontain the same number of molecules.

Avogadro's NumberThe number of molecules in one mole or gram molecular weight of a substance (6.0221367 X 1023 molecules/gm mole).

AzeotropeA mixture of two substances that typically cannotbe separated easily by simple distillation. Also, a commonly used term to describe a liquid mixture that has a constant boiling point.

BalanceAlso known as balance gas.

Blend AccuracyAlso known as process accuracy, this is the degree of statistical agreement between theblended and the true concentration for a com-ponent of a gas mixture (usually at the 95%confidence level), or the certainty or surenesswith which the blended concentration is known.Blend accuracy can be calculated because Air Liquide gravimetric measurement requiresactual data for scale calibration, resolution andweight uncertainties.

Blend ToleranceThe degree of agreement between the blendedconcentration and the requested concentration fora component. Blend tolerance is not determinedby statistical means (whereas blend accuracy is).

Blended ConcentrationThe numerical concentration assigned to acomponent based on the results of blending.A blended concentration is expressed in bothconcentration units (i.e. percent, parts per million)and concentration basis (i.e.mole/mole, weight/weight). A blended concentration may also beaccompanied by a blend accuracy value (i.e. ±2%).

BlendingA process by which component and balancegases of a gas mixture are metered into a container. Blending process measurements (i.e. scale resolution, actual weight data, partialpressures, ACUBLEND™ response data) havesufficient resolution and accuracy to assure thatcomponents are in the required ratio to meetcustomer and Air Liquide specifications.

Boiling Point (BP)The temperature of a liquid at which the vaporpressure is equal to the pressure of the atmos-phere above it.

Bourdon TubeA curved metal tube commonly used in pressuregauges. The tube flexes a known degree aspressure is applied and that movement is trans-lated as the physical movement of a gaugeneedle across a scale.

British Thermal Unit (BTU)A unit of energy defined as the quantity of heatneeded to raise the temperature of one poundof water 1°F.

Burst PressureThe designed test pressure at which a gas containment device (i.e. cylinder, piping, pressureadjusting device) will begin to leak but not violently rupture. For most gas handling equipment,the industrial standard of the burst pressure isfour times or 400% of the normal operatingpressure.



Glossary continued


CalibrationA process designed to determine the relationshipbetween detector response and concentrationfor a given component on an instrument. Duringcalibration, one or more samples of known concentration (i.e. standards) are introduced tothe detector and detector response is recordedfor each sample. Calibration may be performedwith reference standards or with calibrationstandards accompanied by reference standardverification.

Calibration CurveA mathematical function produced by regressionof the detector responses recorded during calibration of an instrument. The function describes detector responses over a range ofconcentrations and is used to predict the concentration of an unknown sample based on its detector response.

Calibration GasA gas with an accurately known concentrationthat is used as a comparative standard in analytical instrumentation.

Calibration Gas StandardA gas mixture accurately analyzed against aknown reference standard. This mix can be usedas a comparative standard for determinationson analytical instruments.

Calibration RangeA range between the highest and lowest con-centrations of standards used for calibrations,from which the concentrations of unknownsamples can be determined. A concentrationrange may be further limited by precision andaccuracy requirements.

CalorieThe amount of heat required to raise the tem-perature of one gram of water at 15°C by 1°C(59°F by 34°F).

Carrier GasThe gas that flows through a separation column of a gas chromatograph and propels a sample to a detector.

CAS NumberA Chemical Abstract Services numbering systemassigned to each new chemical as it is reportedin the world's literature. Virtually every commer-cially manufactured chemical has been assigneda CAS number allowing easy identification.

CelsiusA temperature scale set up so ice melts at 0°C(32°F) and water boils at 100°C (212°F).

Certificate of AccuracyA document that represents the certified con-centration of a component and its associatedaccuracy to the customer.
