AN INTRODUCTION TO DIFFERENT TYPES OF GAS CHROMATOGRAPHY

Abstract

Gas Chromatography was introduced traditionally for the first time by James and Martin in 1952. As years went on, gas chromatography was further developed by combining various detectors and was used for different purposes. In this journal, 4 different types of detectors coupled with Gas Chromatography were discussed: Gas Chromatography-Mass Spectrometry (GC-MS), Gas Chromatography - Olfactometry (GC-O), Gas Chromatography - Flame Ionization (GC-FID), Gas Chromatography - Time of Flight (GC-TOF), and also a new column technology: Multidimensional Gas Chromatography (MDGC). Each type is unique and utilized differently since they differ in their end detector. These detectors may further be combined to obtain better identification of volatile compounds.
