GromSil Amino-3 CP is a polar HPLC column from Dr. Maisch HPLC GmbH, packed with fully porous, high-purity silica and bonded with primary amino (–NH₂) groups. This phase is specifically optimized for the separation of carbohydrates and sugar alcohols without derivatization, using normal-phase or HILIC-like conditions. Its high surface activity enables strong hydrogen bonding and weak anion-exchange interactions, ensuring reliable retention and separation of polar compounds.
The column delivers excellent peak shape and reproducibility, particularly when used with acetonitrile-rich mobile phases.
With reliable selectivity and polar retention, GromSil Amino-3 CP from Dr. Maisch HPLC GmbH is the ideal choice for laboratories performing high-resolution carbohydrate and polar compound separations.
