GromSil 100 Amino-1 PR is a polar HPLC column from Dr. Maisch HPLC GmbH, based on fully porous, high-purity silica with a 100 Å pore size and bonded with primary amino (–NH₂) groups. This stationary phase enables strong polar interactions and is particularly suited for normal-phase and adsorption chromatography, especially for separating carbohydrates, sugar alcohols, and other hydrophilic compounds without derivatization.
The phase also offers weak anion-exchange properties, allowing versatile use in both normal-phase and HILIC-like applications under acetonitrile-rich conditions.
This amino-modified phase from Dr. Maisch HPLC GmbH offers reproducible retention and excellent selectivity — ideal for laboratories focused on carbohydrate analysis and other polar compound separations.
