To provide chromatographic packings whereby biological components, etc. which cannot be separated by either ion-exchange chromatography or reversed phase chromatography employed alone can be efficiently separated without deteriorating their activities. Use is made of a packing which contains a charged copolymer and makes it possible to change the effective charge density on the surface of a stationary phase by a physical stimulus while fixing a mobile phase to an aqueous system.
