Gas chromatography (GC), is a common type of chromatography used in analytic 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 be determined). In some situations, GC may help in identifying a compound. In preparative chromatography, GC can be used to prepare pure compounds from a mixture
Gas chromatography (GC) is widely used in power sector, corporation that produce oil immersed electrical apparatus--- Transformer , wire cannula and enterprises—power plant, power supply bureau , other units for gas analyzing like chemical processing of coal and Bruckhausen.
