Column chromatography silica gel 100-200 mesh filtered and purified silica powder

Column chromatography silica gel is a white powder processed from silica gel, primarily composed of silicon dioxide, with stable chemical properties. It absorbs moisture in the air and, due to its differential adsorption and retention times for various substances, enables the separation and purification of different materials. It features short separation time, high sensitivity, clarity, and non-diffusion.

Column chromatography silica gel is mainly used for the removal of aromatic hydrocarbons from petroleum products, selective adsorption and separation of organic gases and liquids; as a catalyst carrier and chromatographic support; and for the preparation of high-purity substances.
