Description

Technical Field

[0001] The utility model relates to the technical field of gel permeation chromatographs, in particular to a liquid storage tank used for gel permeation chromatographs. Background Art

[0002] Gel permeation chromatography is an instrument used in the fields of materials science, chemistry, and chemical engineering. Gel permeation chromatography, also known as size exclusion chromatography, is a liquid chromatography method that uses a solvent as a mobile phase and flows through a porous filler (such as porous silica gel or porous resin) as a separation medium. Gel permeation chromatography is a branch of liquid chromatography. Its separation component is a chromatographic column with a porous gel as a carrier. The surface and interior of the gel contain a large number of holes of varying sizes that penetrate each other. The composition of the gel permeation chromatograph: pump system, (automatic) injection system, gel chromatographic column, detection system and data acquisition and processing system. In the food testing industry, when analyzing pesticide residues and semi-volatile organic compounds in various foods, agricultural products, and aquatic products, organic sample extracts generally contain large molecular substances. If these substances are not removed, the separation efficiency of the chromatographic column will be reduced, the service life of the injection port and the chromatographic column will be shortened, and the data analysis results will be affected. Therefore, effective purification pretreatment must be carried out before analyzing pesticide residues and semi-volatile organic compounds. The traditional pretreatment process is time-consuming and consumes a lot of solvent. Therefore, the application of gel permeation chromatography is an inevitable trend. Especially in third-party professional food testing institutions, GPC has been widely used.

[0003] The liquid storage tank is a structure in the gel permeation chromatograph, which is used to store liquid. In the existing gel permeation chromatograph, the liquid storage tank only serves as a simple liquid storage structure. Therefore, when the existing liquid storage tank stores liquid, the liquid in the liquid storage tank will not flow. Long-term storage often causes the liquid to precipitate, which affects the later use effect of the liquid. Utility Model Content
