Platinum 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 efficient separation of nonpolar and weakly polar analytes that are not well retained on reversed-phase columns.
With its high surface activity and purity, Platinum Si delivers sharp peak shapes, reproducibility, and robustness for demanding chromatographic applications. It is particularly suited for pharmaceutical, chemical, and environmental laboratories requiring reliable normal-phase separations.
Platinum Si combines high-purity silica with strong polar selectivity – the reliable choice for laboratories performing normal-phase HPLC separations.
