Embodiment Construction
[0032] Specific implementation of the present invention, a microchannel based on scanning colorimetric analysis is used for the rapid detection method of organophosphorus pesticide residues. Taking the detection of malathion pesticide residues as an example, the specific implementation mode of the present invention is further described.
[0033] 1. Template design: Use CAXA software to design the dimensions of the transparent base layer, transparent channel layer, and transparent covering layer. The scanner used in the present invention is a ScanMakeri800Plus flatbed scanner, so the template design size does not exceed the scanning range of the scanner used. One of the templates is designed as follows: the size of the entire pesticide residue detection microchannel is 25mm×75mm, the thickness of the channel layer is 3mm, and there are 8 strip channels of 4mm×13mm inside. An equilateral triangle sample tank, both of which simultaneously form a transparent microchannel hole. Th...
