In the embodiment, the first mounting assembly 410 can move along the front-back direction to the inside of the body 100, at this time, the first mounting assembly 410 can move along the left-right direction to the below of the sampling part or the below of the first flow outlet 222 to sample or collect; the first mounting assembly 410 can also move along the front-back direction to the outside of the body 100, at this time, the operator can more conveniently take out the sample container in the first mounting assembly 410.

The plurality of first flow outlets 222 can simultaneously supply sample liquid from the inside of the extraction device 200 to the plurality of sample containers, thereby improving the collection efficiency of the solid-phase extraction and separation automation device.

[0042] It should be noted that in some embodiments, the first mounting assembly 410 is provided with a plurality of rows of first accommodating portions 411, and each row of first accommodating portions 411 is composed of a plurality of first accommodating portions 411. The number of sampling portions and first flow outlets 222 corresponds to the number of rows of first accommodating portions 411.

The sampling needle tube 310 is connected to the moving mechanism 320, and the moving mechanism 320 can drive the sampling needle tube 310 to move relative to the body 100 in the up-down direction.

[0044] Specifically, when the first accommodating portion 411 is placed with a sample container and moves to the direct below of the sampling needle tube 310, the moving mechanism 320 can drive the sampling needle tube 310 to move downward and insert into the sample container.

When the second mounting assembly 210 drives the extraction container to move to the inside of the body 100, it is more convenient to inject sample liquid or extraction solvent into the extraction container. When the second mounting assembly 210 drives the extraction container to move to the outside of the body 100, it is more convenient for the operator to disassemble or replace the extraction container.
