by Eprogen
CATSEC-1000 columns is unique to Eprogen designed specifically for analysis of cationic polymers. CATSEC-1000 columns have a proprietary polymeric bonding chemistry on a 1000Å, 7µ spherical silica support designed for separating linear molecules with molecular weight ranges of 40-1000 kDa. The polymerized coating enables polymers such as polyvinylpyridines to elute according to size and without adsorption. Mobile phases are generally acidic and contain 0.1-0.2M salt to minimize adsorption and ion-exclusion.
