Medical Definition of Column chromatography

1. A form of partition, adsorption, ion exchange, or affinity chromatography in which one phase is liquid (aqueous) flowing down a column packed with the second phase, a solid; the dissolved substances form a partition between the solid and liquid phases depending on the chemical and physical conditions of each phase; the more strongly adsorbed solutes reach the bottom of the column later than the less strongly adsorbed ones.
