Abstract

Gas chromatography is highly effective and versatile analytical technique with numerous scientific applications in field of science and technology. The applications of GC to a number of studies for determining organic compounds from around the world are presented and highlighted its universal use and acceptance. Many volatile and semi volatile compounds such as residual monomers, solvents and plasticizers and low molecular weight additives antifoaming agents can easily be analyzed by GC. GC is likewise utilized technique as a part of numerous environmental and forensic labs since it takes into consideration the detection of very small quantities. GC is sensitive, accurate, reproducible, quantitative and versatile tool well adapted for the analysis of complex mixture using various detectors. These techniques play an important role in analysis of drugs and pharmaceutical products. However, the use of GC is limited up to volatile and thermally stable compounds or the molecules that may undergo derivatization reactions to thermally stable products.
