ReproSil-Pur 120 Si is an unbonded, high-purity silica HPLC column with a 120 Å pore size, designed for normal-phase and adsorption chromatography. Its active silanol groups provide strong polar interactions, enabling efficient separation of nonpolar and weakly polar analytes that are not well retained on reversed-phase columns.
The use of ultra-pure silica minimizes secondary interactions and ensures sharp peak shapes, reproducibility, and long operational lifetimes. ReproSil-Pur 120 Si is ideally suited for pharmaceutical, chemical, and environmental laboratories requiring robust normal-phase separations.
ReproSil-Pur 120 Si combines high-purity silica with robust polar retention – the dependable choice for laboratories performing normal-phase HPLC separations.
