GromSil 120 Diol is a polar HPLC column from Dr. Maisch HPLC GmbH, based on high-purity, fully porous silica with a 120 Å pore size and bonded with diol (–CH₂OH–CH₂OH) functional groups. This stationary phase enables hydrogen bonding and dipole-dipole interactions, making it ideal for normal-phase chromatography as well as HILIC-like separations of polar and hydrophilic analytes.
Its deactivated surface provides improved peak shapes and reduced tailing for hydroxyl-rich and polar compounds such as sugars, amino alcohols, and polar drug substances.
Offering stable retention and polar selectivity, GromSil 120 Diol from Dr. Maisch HPLC GmbH is the ideal choice for laboratories working with uncharged, hydrophilic compounds in normal-phase or HILIC modes.
