REVIEW ON GAS CHROMATOGRAPHY & ITS HYPHENATION TECHNIQUES

Dr. Nutan Rao* and Kajal D. Gawde

Abstract

Gas chromatography is a powerful separation technique for gas and vapour mixtures. Combining, separation and on-line detection permits accurate quantitative analysis of complex mixtures, including traces of compounds as low as parts per trillion in some particular cases. The importance of gas chromatography in quality control and process control in the chemical and drug industry, in environmental pollution investigations and in clinical analysis is critical. The review describes gas chromatography and its hyphenation techniques.

Keywords: Gas Chromatography, Hyphenated Techniques, Detectors, column, carrier gas.
