[0002] Most pesticide residue detectors now use the colloidal gold detection method. The colloidal gold detection method is to drop the sample to be tested into the sample slot of the colloidal gold detection card and let it stand for a period of time. The sample will react with the colloidal gold labeled reagent, and then specifically bind to the antigen or antibody and be retained, and aggregate to form a reaction identification line on the visual window of the detection card. The reacted detection card is then inserted into the irradiation slot of the detector for detection. Finally, the image of the color display area of the detection card is captured through the camera lens of the detector, and the enlarged image is analyzed and displayed through the body image analysis and processing chip connected to the display screen to determine the analysis result.
