Gas chromatography is a kind of separation technique in which the compounds of a gaseous and volatile substance. Samples are separated on the stationary phase held in Column. In this technique, the component of a sample is dissolved in a solvent. The solvent is vaporized in order to separate the compound or analytes by distributing the sample between two phases: Stationary Phase and mobile Phase. The mobile phase is a chemically inert gas that travels the molecules of the analyte past the heated column. In gas chromatography generally, mobile phases do not interact with the analyte. If the stationary phase is solid absorbent, it is called gas-solid chromatography or if the stationary phase is liquid absorbent, it is called gas-liquid chromatography. Gas chromatography is not traditional because of the limited number of stationary phases. In gas chromatography technique gas-solid chromatography is used with only less solubility of a solute in stationary phase (it is rare). Therefore, in most cases, gas-liquid chromatography is used. It is an instrumental approach or method used forensically in drug analysis, arson, toxicology, and food analysis.
