GromSil Sapphire 110 Si is a normal-phase HPLC column from Dr. Maisch HPLC GmbH, based on ultra-high-purity, fully porous silica with a 110 Å pore size and a highly uniform surface. This unmodified silica phase provides strong polar retention through active silanol groups and is ideally suited for adsorption chromatography, the separation of polar analytes, and sample loading in preparative LC.
The intermediate pore size offers optimal retention and mass transfer for small to medium-sized polar compounds, with excellent mechanical stability and reproducible retention behavior.
With its high-purity silica and robust retention profile, GromSil Sapphire 110 Si from Dr. Maisch HPLC GmbH is a dependable choice for laboratories focused on normal-phase and polar compound separations.
