An important chromatographic separation method is column chromatography (SC). The most common method is liquid chromatography consisting of a mobile phase (liquid or gaseous) and a stationary phase (e.g. solid packing material in a cylindrical tube). Due to the varying degrees of adsorption of the substance to be separated (in the mobile phase) on the stationary phase, preparative purification of substance mixtures of different polarity is achieved, for example.
