Array-type 96-channel rapid detector for pesticide residue

Abstract

The invention discloses an array-type 96-channel rapid detector for pesticide residue, which comprises a casing. A front panel of the casing is provided with an LCD screen and a plurality of keys; the upper surface of the casing is provided with a printer and a cover plate of a 96-channel sample-detection module; the rear part of the casing is provided with a power socket, a power switch and an RS232/USB interface; and the 96-channel sample-detection module, a microprocessor and a power source are arranged inside the casing, wherein the 96-channel sample-detection module of the 96-channel rapid detector for pesticide residue is formed by combining two 48-channel detection modules; a module light source is an array-type light source which integrates and combines 96 light-emitting diodes 412 nanometers in wavelength; a module detector is an integrated-type array combination of 96 photoelectric sensors; and the array-type light source and the array-type detector are in one-to-one correspondence of arrangement mode and cooperate with each other. The rapid detector can rapidly detect the content of organophosphorus and carbamate pesticide residue in foods, vegetables, fruits and water so as to guarantee the safety of eaters.

Description

technical field [0001] The invention relates to a simple, sensitive and rapid analysis instrument, in particular to a rapid analysis instrument for on-site rapid and quantitative detection of pesticide residue content. Background technique [0002] With the continuous deepening and development of economic globalization, the safety of fruit and vegetable pesticides has attracted more and more attention from governments, international organizations, industry organizations, industry experts and even ordinary people. Pesticide residues refer to trace amounts of pesticides that remain in the environment and in organisms, including pesticide precursors, residual metabolites, degradation products, and impurities. Some of the pesticides applied to crops are attached to the crops, some are scattered in the soil, air and water environment, and some of the pesticides remaining in the environment will be absorbed by plants. Pesticide residues reach humans and animals directly through p...

Problems solved by technology

Therefore, there is an urgent need in the market for an instrument that can detect multiple samples at the same time. At present, most of the multi-channel pesticide residue detectors on the market use microplate readers modified. Among the 96 channels, 8 channels must be used each time. Blank detection, so only 88 samples can be tested. Since the 8-channel sequentially moving microplate is used for detection, not only is it inconvenient to use and operate, but the microplate is always moving, which makes the consistency of the test results very poor.
