Thin layer chromatography is a type of liquid chromatography that is used to separate non-volatile mixtures such as glycerine into its individual components. The process is performed on a sheet of glass, plastic, or aluminium foil coated with a thin layer of adsorbent material like silica gel, aluminium oxide (alumina), or cellulose (known as the stationary phase).

Based on the principle of selective adsorption, the chemical mixtures are passed through a column of an adsorbent material and separated into its individual components.
A typical column chromatography system consists of a solid stationary phase like glass, silica gel, alumina or cellulose, and a liquid mobile phase.
