Ultrasep ES Aminotetraol is a silica-based HPLC column featuring an aminotetraol bonded phase, designed for enhanced selectivity towards strongly polar and hydrophilic analytes. The multiple hydroxyl functionalities combined with amino groups provide strong hydrogen-bonding capacity, enabling efficient separation of carbohydrates, sugar alcohols, and other highly polar substances.
This phase significantly reduces peak tailing compared to traditional amino columns, delivering sharper peaks, improved resolution, and reproducible results. Its robust bonding chemistry ensures long column lifetimes, making Aminotetraol a reliable solution for demanding polar separations in food, pharmaceutical, and biochemical analysis.
Ultrasep ES Aminotetraol combines advanced aminotetraol chemistry with robust performance – the reliable choice for laboratories focusing on polar and hydrophilic compound separations in HPLC.
