Pesticide residue detection equipment

Abstract

The invention provides pesticide residue detection equipment. The pesticide residue detection equipment comprises a portable box with an interior accommodating space and an external data processor, and is characterized in that a detection inlet, a thermostat, an enzyme reactor and a liquid discharge groove are sequentially arranged in the box along the flowing direction of a detected liquid, and a calorimetric sensor electrically connected with the external data processor is arranged on the enzyme reactor. According to the pesticide residue detection equipment provided by the invention, the whole detection module is integrated and located in the portable box and convenient to carry, the zero calibration is carried out at first before field detection, a sample liquid only needs to be sampled and added from a sample liquid inlet during the field detection, residue amounts are detected by virtue of a principle of inhibiting enzyme activity by organophosphorus pesticides during an enzymatic reaction process, so that a heat effect is reduced, the changes of the heat effect are acquired by the calorimetric sensor, the processor is used for analyzing, and the rapid and accurate field detection for pesticide residues is finally realized.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for rapid detection of pesticide residues. Background technique [0002] Organophosphorus pesticides are widely used in agricultural production. They have high acute toxicity and cause greater harm to the environment and human health. Recently, the problem of excessive organophosphorus pesticide residues has brought serious hidden dangers to food safety. Control pesticides One of the most effective methods for residues is to strengthen the detection of pesticide residues. In the existing food safety detection process, complex pretreatment is often required, and it is difficult to achieve on-site detection, which brings problems such as high detection cost and long detection cycle. Obstructing the popularization of the development of the detection of agricultural residues, the present invention is aimed at improving this defect of the existing detection equipment, and propo...

Problems solved by technology

[0002] Organophosphorus pesticides are widely used in agricultural production. They have high acute toxicity and cause great harm to the environment and human health. Recently, the problem of excessive organophosphorus pesticide residues has brought serious hidden dangers to food safety. One of the most effective methods for residues is to strengthen the detection of pesticide residues. In the existing food safety detection process, complex pre-treatment is often required, and it is difficult to achieve on-site detection, which brings problems such as high detection cost and long detection cycle. The popularity of the development of pesticide residue detection has been hindered. This invention aims at improving this defect of the existing detection equipment and proposes a portable detection equipment for fast and accurate detection.
