Abstract

The invention discloses a high-flux tea tree organophosphorus pesticide residue detection device based on radial flow sample introduction, and belongs to the field of biological detection.The high-flux tea tree organophosphorus pesticide residue detection device comprises a base, a lamp strip and a camera are installed on the top wall of the base, and a support stand column is installed at the edge of the top wall of the base; and a paper chip bearing table, a funnel frame, a water pipe fixing frame, a control box, an annular support and a Z-shaped support are sequentially fixed to the support stand column from bottom to top, a microprocessor and a circuit board are arranged in the control box, wire inlets are reserved in the centers of the upper surface and the lower surface of the control box, and the control box is connected with a peristaltic pump, an adjusting mechanism, a radiation flow liquid separation device and a PTC heating plate through a plurality of wires. According to the invention, high-flux tea pesticide residue detection can be realized, pesticide residues on the surface of tea can be more thoroughly eluted, the whole reaction process is automatically carried out, manual reagent addition is not needed, manual operation is reduced, errors are reduced, the detection efficiency is high, whether the organophosphorus pesticide in a sample exceeds the standard or not is intelligently judged, the detection result can be displayed in real time, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of biological detection, in particular to a high-throughput detection device for organophosphorus pesticide residues in tea trees based on radial flow sampling. Background technique [0002] In recent years, as people pay more and more attention to food safety issues, the problem of pesticide residues in agricultural products has become a hot spot of widespread concern by scholars at home and abroad. my country has also issued a series of standards for the use of pesticides in agricultural products. Tea has the characteristics of weak insect resistance and no-cleaning, which makes it easier for the pesticide residues in tea to be ingested by the human body and endanger public health. Therefore, the control of pesticide residues in tea is very important, and it is urgent to develop an easy-to-operate, easy-to-populate, high-efficiency, high-throughput detection technology for pesticide residues in tea trees. ...
