Preparation of Microparticles of Narrow Distributed Diameters and Their Usage in Amino Acid Analysis

Abstract

Abstract: The narrow distributed polymeric microparticles with diameters of,3-10 μm were prepared by suspension polymerization when PVA and DBS-Na were used as the mixed dispersant with the rate of stirring 1500-2000 r/min. The effects of the conditions of the polymekrization reactions on the diameters and their distributions of the microparticles were examined. Thereafter, the authors studied the properties of the sulfonated polymeric microparticles which were used as the stationary phases of an amino acid analyzer.

Key words: Suspension polymerization, Microparticle, Stationary phase
