Description

Technical Field

[0001] This utility model relates to the technical field of liquid chromatography columns, specifically to a liquid chromatography column cleaning device. Background Technology

[0002] A liquid chromatography column is an instrument used for liquid chromatography analysis. The mobile phase in a liquid chromatography column contains inorganic salts, which can easily remain inside the column. If these salts precipitate out, they can cause significant damage to the liquid chromatography column. Therefore, a cleaning device is used to clean the liquid chromatography column to ensure its service life and the accuracy of the test results.

[0003] However, existing cleaning equipment only performs flow cleaning of the liquid chromatography column after installation. If the column contains highly retained residues, these residues may not be eluted under the original mobile phase, affecting cleaning efficiency and post-cleaning quality. Therefore, there is an urgent need to design a liquid chromatography column cleaning device to solve these problems. Utility Model Content

[0011] Preferably, the lifting structure includes two first slide grooves, both of which are formed on the surface of the operating table. A sliding rod is movably installed inside each of the two first slide grooves. A movable frame is slidably connected to the surface of the sliding rod, and the rotating frame is rotatably installed at one end of the movable frame.

[0015] Preferably, both of the sliding rods have a rotating shaft movably mounted at their ends, and the surface of the rotating shaft is fitted with a toothed belt.

[0016] By adopting the above-mentioned utility model, when the first motor rotates, the toothed belt can drive the two rotating shafts to run in the same direction, so that the moving frame can be raised and lowered smoothly.

[0017] Preferably, both sides of the operating table are movably equipped with drying structures for drying the cleaned liquid chromatography column. The drying structure includes an adjusting rod, a movable plate is movably mounted on the surface of the adjusting rod, and an electric heating box is fixedly mounted on the surface of the movable plate.

[0018] By adopting the above-mentioned utility model, after cleaning, the electric heating box can be flipped to the front by adjusting the rod to perform a certain drying operation on the liquid chromatography column, thereby accelerating the drying process.
