Problems solved by technology

[0003] In the process of sample pretreatment, laboratory staff often encounter the following technical problems: 1. The liquid passing speed of the sample solution in the solid phase extraction column is slow; 2. It is impossible to accurately control the flow of the sample solution in the solid phase extraction column Third, when the same sample solution is divided into multiple solid phase extraction cartridges for solid phase extraction, it is impossible to ensure that the liquid passing speeds of all solid phase extraction cartridges are consistent
The above technical problems not only affect the convenience of experimental operation, but also often affect the accuracy of experimental results

Abstract

The invention discloses a solid phase extraction pressurizing device which comprises a sliding table. A piston is arranged in each pressurizing sleeve on a supporting seat on the sliding table, a pressurizing cavity is formed between each piston and a closed end of the corresponding pressurizing sleeve, the outer end of a piston rod on each piston is fixedly mounted on a mounting seat, a gas pipe is connected with the closed end of each pressurizing sleeve, one end of each gas pipe is communicated with the corresponding pressurizing cavity, the other end of each gas pipe is used for being communicated with a small solid phase extraction column, and each pressurizing sleeve on the supporting seat can be driven by a sliding driving mechanism on the mounting seat to move back and forth on the outsides of the corresponding piston and the corresponding piston rod, so that the volume of the pressurizing cavity in each pressurizing sleeve can be driven to be gradually reduced or gradually increased, and gas in each pressurizing cavity can be squeezed into the corresponding small solid phase extraction column when the volume of the pressurizing cavity is gradually reduced. The solid phase extraction pressurizing device has the advantages that the solid phase extraction pressurizing device is convenient to use, the experiment speeds can be increased, and the experiment accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of solid phase extraction in laboratories. Background technique [0002] Solid phase extraction is a sample pretreatment technology, which is widely used in experiments in food testing, environmental analysis, pharmaceuticals and other fields. A solid phase extraction column needs to be used in the solid phase extraction operation. The solid phase extraction column has an upper port and a lower port, and a filler is arranged in the solid phase extraction column. In the solid phase extraction operation, the sample solution is transferred to the activated solid phase extraction column, and the sample solution flows out from the lower port of the solid phase extraction column after passing through the filler. [0003] In the process of sample pretreatment, laboratory staff often encounter the following technical problems: 1. The liquid passing speed of the sample solution in the SPE cartridge is slow; 2. It is...
