[0002] A chromatographic column is an instrument used for separating compounds. Different fillers are selected according to the compounds that need to be separated to achieve good results. Among them, silica gel fillers are the most widely used in chromatography technology because they are superior to other fillers in terms of efficiency, hardness and performance. The existing method of producing silica gel fillers is generally to produce semi-finished silica gel particles in a tank with stable temperature and pressure, and then produce silica gel fillers that can be used in chromatographic columns through subsequent processes such as aging, acid soaking, water washing and drying.
