Abstract
Description
Technical Field
[0001] This utility model relates to the field of chromatography column technology, and in particular to a bubble interception device applied to chromatography columns. Background Technology
[0002] A chromatography column is the core device in chromatography used to separate and purify mixtures. It is typically a tubular container with a certain length and inner diameter. Its structure and function are designed to provide a controllable space for the interactions between different components in the sample and the stationary and mobile phases. The closed tubular structure constrains the path of the mobile phase, ensuring uniform packing of the stationary phase. As the sample components migrate with the mobile phase, differences in the intensity of their interaction with the stationary phase lead to variations in migration speed, ultimately causing them to flow out of the column sequentially. This achieves the separation, analysis, and purification of the target components.
[0003] The bubble interception device of the chromatography column clamps the chromatography column to eliminate gaps, prevent leakage of mobile phase, and ensure the continuity of the experiment. At present, chromatography columns are mostly handled manually, and the mobile phase will leak in the gaps. This not only wastes a lot of mobile phase, but also causes the sample to be lost after separation. As a result, trace amounts of sample may be lost directly, leading to experimental failure and increasing experimental costs. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a bubble interception device for chromatography columns, which aims to improve the problem of leakage of mobile phase in gaps in the prior art. This not only wastes a large amount of mobile phase, but also causes the sample to be lost after separation, which may result in the complete loss of trace samples, leading to experimental failure and increased experimental costs.

Since the threaded rod 5 is fixed by the first fixed rod 6 on the inner wall of the fixed block 3, the fixed T-shaped rod 7 is moved back and forth. When the fixed T-shaped rod 7 moves back and forth, the left and right sides of the fixed T-shaped rod 7 are stuck by the T-shaped groove 9 on the inner wall of the sliding block 8, causing the sliding block 8 to move left and right in the sliding groove 13 on the inner wall of the fixed block 3.

[0042] When the bubbly liquid is poured into the first conduit 208, the motor 201 is started, driving the first bevel gear 202, which in turn drives the second bevel gear 203. The second bevel gear 203 then causes the cylinder 205 to start centrifugal rotation via the round rod 204, thus causing the bubbly liquid to rotate. The rotation begins to separate the liquid and the bubbles. The liquid falls through the filter cylinder 207 into the inner wall of the hollow cylinder 209, while the bubbles rise through the first conduit 208. The liquid then falls through the second conduit 211 inside the hollow cylinder 209, thus achieving the effect of bubble interception.
