ABSTRACT

Gas chromatography is the general term for a range of analytical separation techniques used to analyze volatiles in the gas phase. Gas chromatography separates the analytes by separating the sample into two phases, the stationary phase and the mobile phase, by dissolving the sample components in a solvent and evaporating them. The mobile phase is chemically inert Gas, which transports the analyte molecules through the heated column. Gas Chromatography is one of the only chromatographies that interacts with analytes without the use of Mobile phases. The stationary phase is either a solid adsorbent, called Gas-Solid Chromatography (GSC), or a liquid on an inert support, called Gas-Liquid Chromatography (GLC). Gas chromatography is an instrumental technique used forensically in drug analysis, arson, and toxicology analysis of other organic compounds.
