Adsorbosphere HS Si is an unbonded, high-purity silica phase designed for normal-phase chromatography and adsorption-based separations. As part of the HS (High Surface) line, it offers an optimized surface with controlled silanol activity and enhanced separation efficiency for polar compounds, isomers, and neutral organics.
Its high surface area and finely tuned particle morphology make Adsorbosphere HS Si ideal for classical normal-phase methods as well as specialty separations that rely on polar interactions and hydrogen bonding.
Adsorbosphere HS Si is a reliable high-selectivity silica phase — ideal for classical polar retention mechanisms in normal-phase and adsorption chromatography.
