Fully AutomatedSample Preparation System

for POPs Analysis

Features

SelectivityGO-EHT significantly improves selectivity andsensitivity of dioxins and PCBs analysis. As shown in figure 1, some interferences cannot be eliminated by a classical clean-up method.In contrast, with GO-EHT automated samplepurification these interferences are clearlyresolved (fig 1) improving the selectivity and sensitivity of your analysis.

AdvantagesThe GO-EHT Fully Automated Sample Preparation System offers highly purified extracts for precise results of your dioxin and PCB analysis while utilizing a minimal amount of solvent and a short turnaround time.

#157Classical clean-up Fully automated fractionationThe of GO-EHT technology is designed to efficiently deliver concentrated dioxins and PCBs fractions by using special surface-treated adsorbents in its concentration columns.

GC vial volume of dioxin and PCB fractionsThe final fraction volumes are extremely small: 1-2mL, enabling you to move on to the measurement step immediately, which increases workflow efficiency.

Less than 100 ml of solvent per sampleA typical purification process for dioxins and PCBs analysis requires only 90 mL of hexane and 5mL of toluene, without dichloromethane. This system is both user- and eco-friendly.

Heated purificationHeating promotes chemical reactions between the sample and GO-EHT purification columns which contain chemically modified silicagel. Interfering sample constituents are efficiently removed and selectivity of dioxins and PCBs analysis is significantly improved.

No cross contamination in the valveless systemThere are no solenoid valves on the DXNs and PCBs sample flowlines. All columns and tubings are disposable and as a resultthere is no contact between the sample and the system.

VersatilityAdequate columns and methods enables handling a wide varietyof samples. Purification channels operate independantly and/orsimultaneously for maximum flexibility.

Method editorIt is possible to create new methods in addition to the standard methods.

Guaranteed qualityQuality performance is guaranteed for each lot and certificates are published on our website.

Validation DataGO-EHT offers purification with excellent robustness; even if the sample intake varies, the RSD is less than 10% in almost all matrices. The purification columns are designed to assure good repeatability and reproducibility for dioxins and PCBs analysis in various matrices such as food, feed (ingredients) and environmental samples. In addition, the recoveries of dioxins and PCBs improve compared to those in classical methods as shown in the bar chart below.）.

Easy and Flexible Control• Able to handle up to six units independently and/or at

the same time.• Controls based on the highly reliable ‘Programmable

Logic Controller’• User-friendly touchpad and clear screen design.• Possible to back up and restore all data.
