[Development of polymers for high performance ion-exchange chromatography and their application to analysis of human...

The versatility of 4-vinylpyridinium (4VP-EG-Q) and quaternized dimethylaminomethylstyrene (PDAMS-Q) polymers synthesized by suspension copolymerization as column packings for high performance ion-exchange chromatography was described. The proposed polymer columns afforded resolution of human/bovine serum albumin components, such as mercaptalbumin and nonmercaptalbumin. It was suggested that the physicochemical structure on the external surface of the ion-exchangers was very important in the resolution. The characteristics of 4VP-EG-Q column were effectively applied to the investigation of the metal-albumin complexes, whereas a rapid analysis of mercaptalbumin in the human serum using the PDAMS-Q column was performed by isocratic elution.
