Chromatography is carried out in laboratories to distinguish chemical compounds from other unidentified liquid sample. The sample is homogenously mixed with a solvent and is passed through a tube. The sample is strictly divided by the pull of the compound adjacent to the substance of the tube more precisely by the participating force whose polar and non-polar attraction differentiate between the sample and the solvent. The two types of chromatography widely used in recent times are gas chromatography (GC) and used high performance liquid chromatography (HPLC). Gas chromatography vaporizes the tester substance and is processed along with the system with a help of an inert gas like helium. The separation is carried with higher efficiency using hydrogen gas. But most of the laboratories prevent themselves from using hydrogen as the gas is extremely inflammable and can cause major accidents.
