Embodiment 1
[0056] Such as figure 1 As shown, the application provides a method for detecting pesticide residues, the method comprising the steps of:
[0057] Step S1, extracting the sample solution to be detected.
[0058] According to a specific embodiment of the present invention, the method for extracting the sample solution to be detected is as follows:
[0059] Step S110, finely crushing the sample to be tested.
[0060] In step S120, the sample to be detected is dissolved in an extraction solvent. The extraction solvent may be a mixed solvent of acetone and methanol, and the mass fraction of acetone and methanol is the same. Extraction solvent, acetone solvent can dissolve most pesticides, and methanol solvent has higher extraction efficiency.
[0061] Step S130, filtering out impurities in the dissolved solution.
[0062] According to a specific embodiment of the present invention, the dissolved solution is sent into a filter extraction tube; the extraction tube includes a filte...
Embodiment 2
[0109] Such as image 3 As shown, the application provides a pesticide residue detection system 100, which includes:
[0110] The extracting unit 10 is used to extract the sample solution to be tested.
[0111] The extraction unit 10 includes a crushing treatment device for finely crushing the test sample; an extraction tube for holding the extraction solvent, and the sample to be tested is put into the extraction tube, the sample to be tested is mixed with the extraction solvent, and the pesticide is dissolved in the extraction tube. In the solvent, the middle layer of the extraction tube is provided with a filter layer. The filter layer filters out the impurities in the solution mixed with the sample to be tested and the extraction solvent. Outflow; concentrating device for concentrating the extracted supernatant.
[0112] The pesticide residue detection device 20 is used to detect the sample solution to be detected.
[0113] The first image acquisition device 30 is used ...
