60-80 mesh silica gel separation and purification adsorbent

Introduction: 60-80 mesh silica gel separation and purification adsorbent is a white uniform granular material, primarily composed of silicon dioxide, processed from silica gel as the raw material. Its main characteristic is the ability to achieve separation and purification by leveraging differences in adsorption retention times of various components in mixtures.

Application: I. Column Chromatography Silica Gel Introduction: Column chromatography silica gel, also known as chromatographic medium, is a high-purity white powder product with a specific particle size distribution range, processed from silica gel. It is widely used in pharmaceuticals, chemicals, botanical extraction, biochemistry, and other industries.

II. Column Chromatography Silica Gel Principle: The separation principle of silica gel chromatography is based on the varying adsorption forces of substances on silica gel. Substances with higher polarity interact strongly with silica gel, resulting in longer retention times, while those with lower polarity interact weakly, leading to shorter retention times. Through repeated adsorption and desorption processes between the stationary and mobile phases, substances are separated.

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