Description

Technical Field

[0001] The utility model relates to the technical field of pesticide residue detection, in particular to an integrated pre-processing machine for pesticide residue detection. Background Art

[0002] Pesticide residues refer to the trace amounts of pesticide precursors, toxic metabolites, degradation products and impurities that remain in organisms, agricultural and sideline products and the environment after pesticide use. Before pesticide residue detection, samples generally need to be pre-treated, and the pre-treatment mainly includes two steps: supernatant extraction and concentration. Among them, the supernatant extraction process is generally to manually put the sample and solvent into the sample tube, and then manually shake the sample tube to fully dissolve the components in the sample, and finally let it stand and settle. The upper layer of the solution is the required supernatant; the concentration process is generally to manually put the supernatant into a nitrogen blower, and the nitrogen blower evaporates and concentrates it.

[0003] The existing similar pre-treatment integrated machine for pesticide residue detection cannot extract different amounts of supernatant when in use. At the same time, when the supernatant is transferred to the nitrogen blowdown instrument and concentrated by the nitrogen blowdown instrument, the harmful gas emitted is easily inhaled by the human body and affects human health. Therefore, in order to solve the above problems, we need to design an integrated pre-treatment machine for pesticide residue detection. Utility Model Content
