Gas chromatography

From GAWDAwiki

Gas chromatography is a process in which a gas, often nitrogen, combines with a vaporized mixture that is then passed through a long column of adsorbent material to identify its constituents.^[1]The sample is transported through the column by the flow of inert, gaseous mobile phase. The column itself contains a liquid stationary phase which is absorbed onto the surface of an inert solid.^[2]
