ABSTRACT

In the GC technique, the components are dissolved in a solvent and vaporised in order to separate the analytes by dispersing the sample between two phases: a stationary phase and a mobile phase. The analyte molecules are carried through the heated column by the mobile phase, which is a chemically inert gas.Gas chromatography is one of the few chromatographic techniques that does not use the mobile phase to interact with the analyte.The stationary phase is either a solid adsorbant, as in gas-solid chromatography (GSC), or a liquid on an inert support, as in gas-liquid chromatography (GLC). Detectors used in this technique include FID, ECD, TCD, and others. The validation technique is used in the GC Gas chromatography instrumental technique, which is used forensically in drug analysis, arson analysis, and toxicology analyses of other organic compounds.
