    Comment Gas chromatography is always carried out in a column. It is a common type of chromatography used in organic chemistry for separating and analysing compounds that can be vaporised without decompositionIn gas chromatography the distinction between gas-liquid and gas-solid may be obscure because liquids are used to modify solid stationary phases, and because the solid supports for liquid stationary phases affect the chromatographic process. For classification by the phases used, the term relating to the predominant effect should be chosen.See also:- gas chromatography/mass spectroscopy (related) [ IATE:1295813 ]- gas chromatographic separation (related) [ IATE:1094399 ]- gas-liquid chromatography (narrower) [ IATE:1479581 ]- gas-solid chromatography (narrower) [ IATE:1717974 ]

    gas chromatography with an electron capture detector | Gas Chromatography / Electron Capture Detection
    en
    Definition gas chromatography method associated with a detector which uses a radioactive beta emitter (electrons) to ionise some of the carrier gas and produce a current between a biased pair of electrodes, so that when organic molecules that contain electronegative functional groups, such as halogens, phosphorous, and nitro groups pass by the detector, they capture some of the electrons and reduce the current measured between the electrodes Reference COM-Terminology Coordination, based on:Shimadzu GC-8A with ECD Detector: Gas Chromatography.
