Analytical
Chemistry
– Analytical chemistry deals with separating, identifying,
and quantifying the relative amounts of the components of an analyte.
– Analyte = the thing to analyzed; the component(s) of a sample
that are to be determined
The role of analytical chemistry: central science
The relationship between analytical chemistry and the other
sciences

Pharmaceutical
analysis and its scope
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. Bio analytical 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.
