Definition: The separation of chemical substances and particles (originally plant pigments and other highly colored compounds) by differential movement through a two-phase system. The mixture of materials to be separated is percolated through a column or sheet of some suitable absorbent (an ion-exchange material); the substances least absorbed are least retarded and emerge earliest; those more strongly absorbed emerge later.
Synonym(s): absorption chromatography
