GromSil 60 Diol is a polar HPLC column from Dr. Maisch HPLC GmbH, based on high-purity, fully porous silica with a 60 Å pore size and bonded with diol (–CH₂OH–CH₂OH) functional groups. The small pore diameter and high specific surface area provide strong retention of polar and hydrophilic analytes via hydrogen bonding and dipole-dipole interactions.
This phase is particularly suited for normal-phase and HILIC-like applications involving sugars, sugar alcohols, and other hydroxyl-rich compounds. Its low surface activity also supports improved peak shape and method robustness.
With its strong polar selectivity and high retention surface, GromSil 60 Diol from Dr. Maisch HPLC GmbH is an excellent choice for laboratories focusing on the separation of hydrophilic compounds in both HILIC and normal-phase modes.
