Ultrasep ES AP is a silica-based HPLC column with an aminopropyl (AP) bonded phase, offering strong polar interaction and hydrogen-bonding capabilities. This chemistry is particularly suitable for carbohydrate analysis, sugar alcohols, and other highly polar analytes, as well as for applications in normal-phase chromatography.
The aminopropyl functionality provides enhanced retention and selectivity for polar compounds while reducing common issues such as peak tailing seen with conventional amino phases. With high reproducibility and stability, Ultrasep ES AP is a robust solution for laboratories focusing on polar separations in pharmaceuticals, food, and environmental testing.
Ultrasep ES AP combines aminopropyl selectivity with robustness and reproducibility – the reliable choice for laboratories performing polar and carbohydrate separations in HPLC.
