Reprobond Si is an unbonded, high-purity silica HPLC column designed for normal-phase and adsorption chromatography. Its active silanol surface provides strong polar interactions, enabling reliable separation of nonpolar and weakly polar compounds that are not well retained on reversed-phase columns. With its high surface activity and robust design, Reprobond Si ensures sharp peak shapes, reproducibility, and long operational lifetimes. It is a dependable tool for pharmaceutical, chemical, and environmental laboratories requiring strong polar selectivity in their separations.
Reprobond Si delivers strong polar selectivity with high-purity silica – the reliable choice for laboratories performing normal-phase HPLC separations.
