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.

Packing material for chromatography having novel characteristic and method for isolation of substance using the same

PTH-amino acids can be analyzed within a short time at a high sensitivity by chromatographically separating said PTH-amino acids with the use of a packing wherein the hydrophilic/hydrophobic balance on the stationary phase surface can be changed by an external signal while fixing the mobile phase to an aqueous system.
