Description

Technical Field

[0001] The invention relates to the technical field of pesticide detection, and in particular to a pesticide component detection device with contactless isolation sampling. Background Art

[0002] At present, the main means of controlling crop diseases, insect pests and weeds is still chemical control, which has disadvantages such as pesticide residues, environmental pollution and pesticide resistance. Pesticide residues in crops and agricultural products are factors that affect food security, environmental safety and human health and cannot be ignored. Before agricultural products are traded in the market and enter the human diet, the pesticide residues in crops and agricultural products need to be tested.

[0003] When testing for pesticide residues on crops, the outer side of the crop needs to be cleaned, and then the middle section needs to be soaked and tested. In this process, most samples to be tested are manually handled, which makes the samples easily contaminated, and the test liquid is easy to volatilize, which not only causes harm to the testers, but also easily causes environmental pollution.
