Ultrasep ES-C10-Omega-COOH is a silica-based HPLC column with a carboxyl-functionalized C10 bonded phase. The unique combination of medium-chain hydrophobicity (C10) and terminal carboxyl groups provides dual retention mechanisms, enabling both hydrophobic and ionic interactions. This design delivers superior selectivity for acidic, polar, and ionizable compounds compared to conventional alkyl phases.
The carboxyl functionality improves peak shapes for polar analytes and enhances method flexibility, while the robust bonding chemistry ensures long lifetime and reproducibility. Ultrasep ES-C10-Omega-COOH is ideal for laboratories requiring advanced selectivity in pharmaceutical, biochemical, and environmental applications.
Ultrasep ES-C10-Omega-COOH offers a powerful combination of hydrophobic and ionic selectivity – the reliable choice for challenging HPLC separations of polar and acidic compounds.
