Core-Shell Silica HPLC Column for Normal-Phase Chromatography

ReproShell Si is an unbonded, high-purity silica HPLC column with core-shell particle technology, designed for normal-phase and adsorption chromatography. Its active silanol groups provide strong polar interactions, enabling reliable separation of nonpolar and weakly polar analytes not well retained on reversed-phase columns. The core-shell particle design ensures high efficiency, reduced backpressure, and sharp peak shapes, allowing faster and more reproducible normal-phase separations compared to fully porous silica. ReproShell Si is particularly suited for pharmaceutical, chemical, and environmental laboratories requiring robust and reproducible polar selectivity.

ReproShell Si combines the robustness of high-purity silica with the efficiency of core-shell technology – the dependable choice for laboratories performing normal-phase HPLC separations.
