ReproKrom 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 effective separation of nonpolar and weakly polar compounds that are not retained on reversed-phase phases. The column delivers sharp peak shapes, high reproducibility, and robust performance, making it suitable for pharmaceutical, chemical, and environmental laboratories requiring reliable normal-phase separations.
ReproKrom Si combines high-purity silica with strong polar retention – the dependable choice for laboratories performing normal-phase HPLC separations.
