Gas Chromatography By Naaimat Muhammed

Gas- liquid chromatography is based upon the partition of the analyte between a gaseous mobile phase and a liquid phase immobilized on the surface of an inert solid. The concept of gas-liquid was first enunciated in 1941 by Martin and Synge, who were also responsible for the development of liquid-liquid partition chromatography. In gas chromatography, the sample is vaporized and injected onto the head of a chromatographic column Elution is brought about by the flow of an inert gaseous mobile phase. Gas-liquid chromatography finds widespread use in all fields of science, where its name despite the fact that this usage neglects gas solid chromatography as a legitimate kind of chromatography
