Quick spectrum detection system for pesticide residues

Abstract

The invention discloses a quick spectrum detection system for pesticide residues. The quick spectrum detection system comprises a shading plate I, a shading plate II, a cuvette reaction array device, a multi-light-source array device, an automatic pesticide residue sample injector, a light receiving probe and an optical fiber spectrometer, wherein the two shading plates are arranged in parallel; the cuvette reaction array device is arranged between the two shading plates; the multi-light-source array device is arranged on the outer side of the shading plate I; the automatic pesticide residue sample injector is arranged on the outer side of the shading plate II; corresponding through holes are formed in the two shading plates; the light receiving probe is arranged in the through hole in the shading plate II and is connected with the optical fiber spectrometer. According to the quick spectrum detection system for the pesticide residues, the cuvette reaction array device, the multi-light-source array device, the automatic pesticide residue sample injector and the like are combined with one another, and a plurality of cuvette insertion slots are formed in a cuvette reaction array bracket, so that a plurality of cuvettes can be detected at a time, or in order to further precisely detect a certain cuvette, the accuracy of qualitative and quantitative detection can be improved according to the characteristic of array crossing response.

Description

technical field [0001] The invention relates to a spectrum detection system, in particular to a rapid detection system for the spectrum of pesticide residues. Background technique [0002] Existing detection methods for micro-trace pesticide residues, in recent years, more commonly used chromatography, including gas chromatography, high performance liquid chromatography, gas-mass spectrometry, liquid-mass spectrometry and other large-scale instrument analysis. These methods can maintain the accuracy and precision of data, but the operation process is complicated, the detection cycle is long, the reagent consumption is large, and professional personnel are required to operate, which has seriously affected the popularization of pesticide detection. [0003] In recent years, scholars at home and abroad have also focused their research on biosensors, which are mainly based on the principle of enzyme inhibition or directly using organophosphate hydrolase detection. AChE can be i...
