Description

Technical Field

[0001] The utility model relates to the field of extraction column design and use, in particular to a solid phase extraction column. Background Art

[0002] The extraction column uses selective adsorption and selective elution to separate and purify samples. The liquid sample solution passes through the adsorbent to retain the substance to be tested, and then a solvent of appropriate strength is selected to flush out the impurities. Then a small amount of solvent is used to quickly elute the substance to be tested, thereby achieving the purpose of rapid separation, purification and concentration. It can also selectively adsorb interfering impurities and let the substance to be tested flow out.

[0003] Generally speaking, the extraction column needs to go through the steps of pre-washing, loading, elution, etc. when in use. It needs to use a variety of solutions, and each step is carried out separately in different time periods. The working process is also relatively long, so the staff needs to wait for a long time. During the waiting process, they can often do other work. If multiple extractions are carried out in parallel, they may confuse the working process when returning to continue working, repeat or omit steps multiple times, and lack work indication function, which will lead to work errors.

[0004] In addition, during the test process, multiple storage bottles are needed to store various solutions, and multiple storage bottles are also needed to collect the liquids completed in each step. The placement of various storage bottles needs to have a relatively strict order, because the solutions in different steps are different, but the color and appearance may be similar, and it is very easy to use errors. Fool-proofing is required for this project to avoid placement errors when taking and placing. Utility Model Content

[0005] The technical problem to be solved by the utility model is that multiple steps lack recording function, which easily leads to repeated operation and missed operation. Multiple storage bottles are easily misplaced when placed and taken out, which causes the wrong pouring of liquid during work and affects the test results.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is a solid phase extraction column, including a column tube and a filler, the filler is arranged in the lower middle part of the column tube, the column tube is surrounded by a step reminder, the step reminder is provided with multiple groups and is used to record each working step, the step reminder includes a recording seat, a sliding card and a toggle buckle, the recording seat is arranged outside the column tube, the recording seat is provided with a sliding groove, the sliding card is slidably arranged on the recording seat and is located in the sliding groove, and the toggle buckle is arranged on the sliding card.

[0007] Furthermore, two groups of prompt points are provided on the recording base.

[0008] Furthermore, an auxiliary tool is included, and the auxiliary tool includes a supporting structure and a mounting structure, the supporting structure is located below the column tube, and the mounting structure is arranged on the supporting structure.

[0009] Furthermore, the support structure includes a base, a support frame and a positioning ring, the base is located below the column tube, the support frame is arranged on the base, and the positioning ring is arranged on the base and located below the column tube.

[0010] Furthermore, the base is provided with a plurality of groups of positioning grooves, and a plurality of groups of storage bottles are placed on the base, and the storage bottles are respectively placed in the positioning grooves.
