SECAT-100 columns are uniquely designed for the analysis of cationic polymers. These columns feature a proprietary polymeric bonding chemistry on a 100Å, 5μ spherical silica support, optimized for separating linear molecules within a molecular weight range of 0.5–25 kDa. The specialized polymerized coating ensures that polymers, such as polyvinyl pyridines, elute based on size without adsorption. Acidic mobile phases with 0.1–0.2 M salt are typically used to minimize adsorption and ion-exclusion, enabling reliable and efficient analysis.
The SECAT-300 column is specifically designed for the analysis of cationic polymers. It features a proprietary polymeric bonding chemistry on a 300Å, 5μ spherical silica support, optimized for separating linear molecules within a molecular weight range of 2–100 kDa. The polymerized coating ensures that polymers, such as polyvinyl pyridines, elute based on size without adsorption. Acidic mobile phases with 0.1–0.2 M salt are typically used to reduce adsorption and ion-exclusion effects.
The SECAT-1000 column is uniquely designed for the analysis of cationic polymers. Featuring proprietary polymeric bonding chemistry on a 1000Å, 7μ spherical silica support, it is optimized for separating linear molecules with molecular weight ranges of 40–1000 kDa. The polymerized coating ensures polymers like polyvinyl pyridines elute according to size, minimizing the risk of adsorption. Typical mobile phases are acidic and include 0.1–0.2 M salt to reduce adsorption and ion-exclusion effects.
