Silica gel adsorbent 100-200 mesh 60A column chromatography silica gel

Column chromatography silica gel is a white powder, primarily composed of SiO₂·nH₂O. It is insoluble in water, inorganic acids, and other organic solvents, but soluble in strong acids and strong bases. It can absorb moisture from the air. Due to its ability to adsorb and retain different substances for varying durations, it enables the separation and purification of various materials.

This product is mainly used for refining petroleum products by removing aromatic hydrocarbons, selective adsorption and separation of organic gases and liquids, serving as a catalyst carrier and chromatographic support, as well as for the separation and purification of active ingredients in Chinese herbal medicine and the preparation of high-purity substances.
