VisionHT Silica is a high-purity, unbonded silica HPLC column, designed for normal-phase and adsorption chromatography. Its highly active silanol surface provides strong polar interactions, enabling effective separation of nonpolar and weakly polar compounds that are difficult to retain on reversed-phase columns.
With multiple particle size options, VisionHT Silica offers flexibility for both high-resolution and routine separations. Its purity, reproducibility, and robustness make it a trusted choice for pharmaceutical, chemical, and environmental laboratories performing normal-phase HPLC.
VisionHT Silica delivers high-purity performance and strong polar selectivity – the reliable choice for laboratories performing normal-phase HPLC separations.
