ReproSil-Pur Basic 100 Si is an unbonded, high-purity silica HPLC column with a 100 Å pore size, designed for normal-phase and adsorption chromatography. The active silanol groups provide strong polar interactions, making this column well suited for analytes that are insufficiently retained on reversed-phase phases.
With its optimized surface and high-purity silica, ReproSil-Pur Basic 100 Si delivers sharp peak shapes, reproducibility, and robust performance in pharmaceutical, biochemical, and environmental applications.
ReproSil-Pur Basic 100 Si provides high-purity silica performance with strong polar selectivity – the reliable choice for laboratories performing normal-phase HPLC separations of small molecules.
