Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of pesticide detection, especially to a pesticide residue detection tube. BACKGROUND
[0002] The detection of organic phosphorus and carbamate pesticide residues in vegetables usually adopts enzyme inhibition detection, that is, choline esterase is used to catalyze the decomposition of indophenol acetate to produce blue indophenol. If the pesticide in the sample inhibits the activity of choline esterase, there is no blue product. Currently, the detection method for organic phosphorus and carbamate pesticide residues in vegetables usually adopts pesticide residue rapid test card method, that is, choline esterase and indophenol acetate are fixed on the rapid test card respectively. After the sample is added to the choline esterase tablet, a certain period of time is required, and then the two pieces of filter paper are folded to contact and react. During the folding process, liquid may be spilled, and if the overlap is not complete, it may cause incomplete contact reaction, resulting in detection error.
[0003] Publication (announcement) No. CN219369577U discloses a pesticide residue detection tube, which comprises a detection tube and a colorimetric card. The detection tube is divided into upper and lower parts for storing different tablets. The upper and lower parts of the detection tube are axially connected and the end faces are fitted to prevent impurities from entering the tube and to prevent the sample liquid in the tube from spilling. The novel pesticide residue detection tube divides the detection tube into upper and lower parts. The lower tube body and the medicine storage box are used to store different tablets. The upper and lower parts of the detection tube are axially connected and the end faces are fitted to prevent impurities from entering the tube and to accelerate the reaction of the sample detection liquid and the tablets. At the same time, the lower tube body and the upper tube body are connected by snap fitting or screw connection to prevent the sample liquid in the tube from spilling during shaking and to ensure the detection result.
