The invention discloses a liquid phase separation chromatography device which comprises a tank body with an inner cavity structure, an upper sealing head and a lower sealing head which are detachably connected to the two ends of the tank body, a chromatography liquid distribution assembly located in the upper sealing head, and a filtering piece located in the lower sealing head, the chromatography liquid distribution assembly comprises a tree-shaped distribution pipe which is communicated with the inlet pipe and is provided with a plurality of through holes, a liquid distribution pore plate positioned below the tree-shaped distribution pipe and a plurality of filtrate columns positioned below the liquid distribution pore plate, a plurality of uniformly distributed liquid distribution holes are formed in the liquid distribution pore plate, and the filtrate columns are positioned between the adjacent liquid distribution holes; a three-layer liquid distribution system is formed through the tree-shaped distribution pipe, the liquid distribution pore plate and the filtrate column, the liquid distribution form and structure of each layer have specificity, and different liquid distribution structures are respectively adopted, so that liquid is uniformly dispersed in the liquid phase separation chromatography device and enters the filter assembly, and a reliable chromatography effect is realized; and internal mechanisms of the column structure of the liquid phase separation chromatography device can be replaced or overhauled according to use requirements, so that the use performance is improved.
Description
technical field [0001] The invention relates to the technical field of chromatographic separation, in particular to a liquid phase separation chromatographic device. Background technique [0002] Liquid separation chromatography is widely used in the fields of chemistry, chemical industry and pharmaceuticals, mainly for the extraction, separation and purification of organic compounds and natural products. However, the structure of the existing chromatography column is complex, and the liquid distribution is centralized during the chromatography process, which leads to the accumulation of liquid at the filtration place in the chromatography column, which easily leads to the problems of poor chromatography processing effect and low chromatography efficiency. In addition, the existing chromatographic columns are all fixed structures, which have high cost, poor usability and relatively complicated operation, and the components in the chromatographic column are not easy to be rep...
