Gas-liquid chromatography is a type of partition chromatography , where the moving phase is an inert gas and the stationary phase is a liquid with a high boiling point absorbed on a solid surface. The sample is injected into the gaseous state. Where the sample evaporates and flows into the liquid phase (column). Separation is done depending on the relative addiction of the elements in the steady state. The components are dissolved due to the splitting of vapor , gas and liquid in the sample .
