ReproSil Star Si from Dr. Maisch HPLC GmbH is a high-purity, fully porous silica HPLC column designed for normal-phase chromatography and applications requiring strong polar surface interactions. With its unmodified silica surface, this column provides excellent retention for polar analytes through hydrogen bonding and dipole–dipole interactions.
It is ideal for separating structural isomers, lipids, and other compounds that are difficult to resolve using reversed-phase methods.
ReproSil Star Si columns from Dr. Maisch HPLC GmbH deliver high-efficiency polar selectivity – the trusted choice for normal-phase and polar compound chromatography.
