WHAT IS ANALYTICAL CHEMISTRY?
Qualitative: provides information about the identity of
an atomic, molecular or biomolecular species
Quantitative: provides numerical information as to the
relative amounts of species
Analytical chemistry seeks ever improved means of
measuring the chemical composition of natural and
artificial materials
The techniques of this science are used to identify the
substances which may be present in a material and
determine the exact amounts of the identified substances
Definitions from www.acs.org
What is Analytical Chemistry ?
- Analytical chemistry deals with separating, identifying, and quantifying the
relative amounts of the components of an analyte.
The Role of Analytical Chemistry
-Friedrich Wilhelm Ostwald
“Analytical Chemistry, or the art of
recognizing different substances and
determining their constituents, takes a
prominent position among the
applications of science, since the
questions which it enables us to answer
arise wherever chemical processes are
employed for scientific or chemical
purposes.”

CLASIFICATION OF ANALYTICAL METHODS
Classical methods: early years (separation of analytes) via
precipitation, extraction or distillation
Qualitative: recognized by color, boiling point, solubility, taste
Quantitative: gravimetric or titrimetric measurements
Instrumental Methods: newer, faster, more efficient
Physical properties of analytes: conductivity, electrode potential,
light emission absorption, mass to charge ratio and fluorescence,
many more…
Several different areas of analytical chemistry:
1. Clinical analysis - blood, urine, feces, cellular fluids, etc., for use in diagnosis.
2. Pharmaceutical analysis - establish the physical properties, toxicity,
metabolites, quality control, etc.
3. Environmental analysis - pollutants, soil and water analysis, pesticides.
4. Forensic analysis - analysis related to criminology; DNA finger printing, finger
print detection; blood analysis.
5. Industrial quality control - required by most companies to control product
quality.
6. Bioanalytical chemistry and analysis - detection and/or analysis of biological
components (i.e., proteins, DNA, RNA, carbohydrates, metabolites,
etc.).
This often overlaps many areas. Develop new tools for basic and
clinical research.

ANALYTICAL PROBLEMS AND THEIR
SOLUTION
The solutions of all analytical problems, both
qualitative and quantitative follow the same
basic pattern which can be described under
seven general headings.
