Gas chromatography is a type of chromatography used in chemistry for analysing and separating compounds that can be convert to gas without decomposition. Uses of this technique include testing the purity of a Gaseous substance and separating the different components of a mixture. Sometimes, it may help in identifying the compound. It can also be used to prepare pure compounds from a mixture. Gas chromatography is similar to fractional distillation, as both processes separate the mixture components primarily based on their vapour pressure differences.
