GromSil 80 Amino-1 PR is a polar HPLC column from Dr. Maisch HPLC GmbH, based on fully porous, high-purity silica with an 80 Å pore size and bonded with primary amino (–NH₂) functional groups. The phase supports strong polar retention via hydrogen bonding and weak anion-exchange interactions, making it well suited for the separation of sugars, polyols, and other hydrophilic analytes.
Its balanced surface activity and pore structure allow efficient retention of small to medium-sized polar compounds in both normal-phase and HILIC-like conditions.
With its polar selectivity and reproducible retention, GromSil 80 Amino-1 PR from Dr. Maisch HPLC GmbH is an excellent choice for analytical workflows targeting hydrophilic substances and structurally related polar analytes.
