Abstract
Abstract Surface reactions of chlorodimethyl [4-(4-chloromethylphenyl)butyl] silane and chlorodimethyl (4-phenylbutyl) silane with small-particle silica, followed by simple chemical modifications, lead to the preparation of weak and strong cation-exchange packing materials for high-performance liquid chromatography. Retention of various solutes on such bonded phases was investigated under different conditions of pH, ionic strength, and mobile-phase composition. Results of these studies are compared with those previously obtained on classical cation-exchange materials under comparable operating conditions.
