Explanation:
Detailed explanation-1: -the characteristic feature of any form of chromatography is the absorption of a stationary phase in another medium. Explanation: in addition to this chromatography is also an important process for the separation of substances of the mixture.
Detailed explanation-2: -Chromatography is a separation process involving two phases, one stationary and the other mobile. Typically, the stationary phase is a porous solid (e.g., glass, silica, or alumina) that is packed into a glass or metal tube or that constitutes the walls of an open-tube capillary.
