Gas chromatography (GC) is an analytical separation technique used to analyze volatile substances in the gas phase. In GC, the components of a sample are vaporized in order to separate the analytes by distributing between a stationary phase and a mobile phase. The mobile phase of gas chromatography is a chemically inert gas used to carry the molecules of the analyte through the column without interacting with the analyte. The stationary phase is either a solid adsorbent, termed gas-solid chromatography (GSC), or a liquid on an inert support, termed gas-liquid chromatography (GLC).
Samples for GC must be volatile, such as human breath, blood, saliva, air samples and other mixtures containing large amounts of organic volatiles, so GC can be used in many different fields including medicine, cosmetics, even environmental toxins, etc.
