Ultrasep ES Amid H-RP18P is a silica-based HPLC column with a polar-embedded amidic C18 bonded phase. The embedded amide group minimizes silanol interactions, providing improved peak symmetry for basic and polar analytes, while maintaining strong hydrophobic retention from the C18 chains.
This phase offers enhanced selectivity, combining hydrophobic and polar interactions, making it particularly useful for complex mixtures, stability-indicating assays, and pharmaceutical analysis. The robust bonding ensures long lifetime, even under harsh pH and temperature conditions.
Ultrasep ES Amid H-RP18P delivers balanced hydrophobic retention, polar selectivity, and excellent robustness – the reliable choice for challenging reversed-phase HPLC separations.
