Description

technical field [0001] The invention relates to a high-efficiency column chromatography system, which is suitable for the separation and purification of active ingredients of traditional Chinese medicine and natural medicine, and belongs to the field of medical equipment. Background technique [0002] Column chromatography is a separation and purification technology widely used in biology, medicine, food and other fields. It is a technical means to separate the mixture according to the different distribution coefficients of the components in the mixture in the stationary phase and mobile phase. Depending on the mechanism of column chromatography, it also includes various forms such as adsorption chromatography, partition chromatography, ion exchange chromatography, and gel filtration chromatography. However, in the application process of existing column chromatography, there are common problems such as low column utilization efficiency, poor stability, and low production cap...
