Description

Technical Field

[0001] The utility model relates to the technical field of wastewater separation, in particular to a wastewater separation device of a solid phase extractor. Background Art

[0002] Solid phase extraction is a sample pretreatment technology developed in recent years. It is developed by combining liquid chromatography technology with liquid-solid extraction columns. It is mainly used for sample separation, purification and concentration. Compared with traditional liquid-liquid extraction, it can improve the recovery rate of analytes. After the extraction is completed, there is usually solvent or wastewater in the test tube. When pouring out the solvent or wastewater, personnel usually pour out multiple test tubes one by one. This process is time-consuming and labor-intensive, and it is easy to accidentally break or smash the test tube during the process of picking up and pouring.

[0003] A search was conducted to find out the above-mentioned problems. In the prior art that has been disclosed, for example, a fully automatic solid phase extractor proposed in publication number CN209714368U, is a solid phase extractor in which a plurality of test tubes are fixedly mounted on a mounting plate, and the mounting plate is rotatably mounted on a fixed frame. A plurality of collecting grooves are opened under the test tubes, and the collecting grooves correspond to two chambers respectively. If there is waste water remaining in the test tube, the mounting plate is rotated to pour the waste water into one of the chambers. If there is a reagent solution in the test tube, the test tube is rotated to the other chamber for pouring. However, when the device is rotated, all the test tubes on the mounting plate are rotated. If the residual substances in the test tubes are different, it is difficult for the device to pour them separately. Therefore, the waste water and the solution may be mixed together in the chamber during the pouring process. Utility Model Content
