gas chromatography gas-solid chromatography 2014-01-14T17:56:27Z An analytical separation technique used to analyze volatile substances in the gas phase. The components of a sample are dissolved in a solvent and vaporized in order to separate the analytes by distributing the sample between two phases: a mobile phase comprised of a chemically inert gas that serves to carry the molecules of the analyte through the heated column, and a stationary phase consisting of a solid adsorbant.
