| Abstract: | A method of preparing porous silica-base microparticle packings for size exclusion chromatography by the agglomeration of silica sols was investigated. After chemical modification of the silica gel,the diol stationary phase was formed. They were used for the separation of proteins. With small particle diameter of these packings, it was advantageous to separate and analyze large biomolecules. |
