ReproSil-XR 120 Si from Dr. Maisch HPLC GmbH is a high-purity, fully porous silica HPLC column with a 120 Å pore size and an unmodified silica surface. Designed for normal-phase chromatography, it provides strong polar surface interactions, delivering excellent retention and selectivity for polar analytes through hydrogen bonding and dipole – dipole interactions. This column is ideal for structural isomer separation, lipid analysis, and other applications where reversed-phase methods offer insufficient retention.
ReproSil-XR 120 Si columns from Dr. Maisch HPLC GmbH deliver high-efficiency polar selectivity – the trusted choice for normal-phase and polar compound chromatography.
