Movable baffle plate for macroporous resin column

Abstract

The invention provides a movable baffle plate for a macroporous resin column. The movable baffle plate for the macroporous resin column comprises a baffle plate main body, a washer and water caps for filtering resin, wherein the baffle plate main body is of a cylindrical structure, a groove is formed in the middle part of the side surface of the baffle plate main body, the washer is nested in the groove, the radius of the periphery of the washer after nesting is slightly more than the radius of the circle of the baffle plate main body, a through hole is formed between the upper surface and the lower surface of the baffle plate main body, a water cap base is fixed in the through hole, and a filtering head of each water cap is arranged on the upper surface of the baffle plate main body. The movable baffle plate for the macroporous resin column has a simple structure and can be used conveniently, resin can be effectively prevented from being washed away and influencing the testing result when a sample is loaded on the macroporous resin column, the sample tailing phenomenon can be avoided when elution is carried out, the washer can be replaced conveniently, and the movable baffle plate has prominent practicability.

Description

technical field [0001] The invention relates to a device for separating and purifying chemical components of traditional Chinese medicine, in particular to a movable baffle for a macroporous resin column. Background technique [0002] The separation and purification of active components of traditional Chinese medicine is an important process link in the modern pharmaceutical industry of traditional Chinese medicine, and an important means to improve the content of active ingredients in traditional Chinese medicine preparations. At present, the separation and purification methods applied to the chemical components of traditional Chinese medicine mainly include macroporous resin adsorption, water extraction and alcohol precipitation, extraction, membrane separation, new adsorbent electrophoresis and chromatographic separation technology, flocculation separation technology and other methods. It has been applied to different degrees in the separation and purification of active i...

Problems solved by technology

[0003] However, macroporous resins are usually prepared by polymerizing monomers (styrene, methyl methacrylate, propionitrile) and additives such as crosslinking agents, porogens, and dispersants, and have a three-dimensional network. structure, the weight is relatively light, when the flow rate of the sample solution is fast, the resin above the resin column will be washed up, resulting in uneven adsorption of active ingredients on the resin adsorption layer, and serious sample tailing during elution
