The present invention relates to the field of chromatography. More closely, the invention relates to a chromatographic method for purification of plasmaproteins, such as Factor VIII, von Willebrand factor and Factor IX. The chromatographic method is performed on a matrix comprising an inner porous core and outer porous lid surrounding said core.

Methods of preparing polymer-filled chromatography resin and their uses are provided.

Ion exchange stationary phases are prepared with diprimary diamines for applications such as separating samples that contain polyvalent anions. The ion exchange stationary phase includes a series of condensation polymer reaction products bound to a substrate. The condensation polymer products are formed with diprimary diamines and polyepoxide compounds. The ion exchange stationary phases described herein are capable of separating monovalent and highly polyvalent anions relatively quickly with relatively low eluent concentrations in one chromatographic run.
