GromSil 60 NP-2 is a normal-phase HPLC column from Dr. Maisch HPLC GmbH, based on fully porous, high-purity silica with a 60 Å pore size and an unmodified (bare) surface. Its high specific surface area and active silanol groups provide strong polar retention and selective interaction with hydroxyl, carbonyl, and amino-functionalized compounds.
This phase is ideal for traditional normal-phase and adsorption chromatography, offering sharp peak shapes, strong retention of polar analytes, and reproducible separations in non-aqueous solvent systems.
With strong polar retention and robust performance, GromSil 60 NP-2 from Dr. Maisch HPLC GmbH is the ideal solution for laboratories using classical normal-phase techniques or adsorption chromatography.
