Gas chromatography or GC is a type of adsorption chromatography. The mobile phase of gas chromatography is a gas. This is the reason why this is termed as “gas chromatography”. The stationary phase can be either a solid adsorbent or a liquid adsorbent.
If it is a solid adsorbent then this is called as “gas-solid chromatography” where as if liquid adsorbent then this is called as “gas-liquid chromatography”. In gas-liquid chromatography a non-volatile liquid has to use. Gas chromatography helps in many ways to detect explosive air pollutants, essential oils and very useful forensic studies.
