Description

Technical Field

[0001] The utility model relates to the technical field of chromatographic columns, in particular to a chromatographic column bracket. Background Art

[0002] Chromatography, also known as chromatography or chromatographic method, is a physical and chemical analysis method that uses the difference in the forces between different samples and the stationary phase and the mobile phase. When the two phases move relative to each other, each solute undergoes multiple equilibriums between the two phases, allowing the solutes to be separated from each other. Separation is the core of chromatography. Therefore, the chromatographic column that is responsible for separation is the heart of the entire chromatographic device. The column efficiency, selectivity and analysis speed of the chromatographic column directly affect the chromatographic effect. When using a chromatographic column, an auxiliary device, a chromatographic column rack, is required. The function of the chromatographic column rack is to place the chromatographic column vertically and ensure the safety of the chromatographic column during use and storage.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN214861368U discloses a bracket assembly that can be used to fix multiple chromatographic columns, including a base, a pillar is arranged on the base, and a plurality of clamping plate assemblies for fixing and clamping the chromatographic columns are rotatably installed at equal intervals on the pillar; the clamping plate assembly includes a cross plate, one end of the cross plate is provided with an opening that is rotatably matched with the pillar, the other end of the pillar is provided with a circular ring for fixing and clamping the chromatographic column, and at least three clamping blocks for clamping the chromatographic column are arranged on the inner side wall of the circular ring. This patent realizes that a plurality of clamping plate assemblies for fixing and clamping the chromatographic columns are rotatably installed on the pillar, and the cooperation of the clamping plate assemblies is selected when using it, so that the same chromatographic column rack can fix multiple chromatographic columns at the same time when in use.

[0005] However, the above patent still has problems that need to be improved during actual use. The most obvious one is the lack of a good buffering process during the clamping and fixing of the chromatographic column, which makes the chromatographic column easily damaged by impact force.

[0006] Therefore, we proposed a chromatography column holder to solve the above drawbacks. Utility Model Content
