Gas chromatography (GC), is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture (the relative amounts of such components can also b...

Gas chromatography is a technique for analysing a mixture of volatile substances in which the mixture is carried by an inert gas through a column packed with a selective adsorbent and a detector records on a moving strip the conductivity of the gas leaving the tube. Peaks on the resulting graph indicate the presence of a particular component.

A method of analysis which separates the various volatile compounds in a liquid and recording the results on a graph. Percentages of each compound are obtained with this method. Although the exact compounds present cannot be determined with GC, it is often done together with Mass Spectrometry, which gives more detailed information.
