Silica Gel 60A Column Chromatography Silica Powder 230-400 Mesh Export Quality

Column chromatography silica gel is processed and manufactured from high-quality silica gel as raw material. Its main characteristic is the ability to achieve separation and purification by leveraging the differences in adsorption retention times of various components in a mixture. It features high purity, safety, and hygiene. It is a colloidal system with solid characteristics, composed of colloidal particles that form an aggregated structure. The colloidal particles are polymers of hydrated silica gel (polysilicic acid) and belong to amorphous substances. The gaps between the aggregates of colloidal particles form the microporous structure inside the particles of column chromatography silica gel. Therefore, it is a high-quality adsorbent material with abundant microporous structure, high specific surface area, high purity, and high activity.
