Selection of Chromatographic Silica GelMacroporoussilica gel is processed and manufactured as the raw material. Its main characteristic is the ability to achieve separation and purification by leveraging differences in the adsorption retention times of various components in a mixture.Chromatographic silica gel is a commonly used separation and purification technique, widely applied in fields such as chemistry, biology, and pharmaceuticals. Chromatographic silica gel is a porous material with a large specific surfacearea and strong adsorption capacity, enabling effective separation and purification of compounds in mixtures.
