Quick detector for microcystic toxins

Abstract

The present invention provides a rapid microcystin detector, which includes an irradiation assembly, a detection assembly, a receiving assembly and a detection liquid preparation assembly, wherein the illumination assembly includes sequentially arranged high-brightness LEDs, optical couplers, Quartz optical fiber and collimator, the detection component includes a Z-shaped flow cell, the Z-shaped flow cell has a detection channel and a detection liquid channel, one end of the detection channel is connected to the collimator of the irradiation component, and the detection liquid channel is connected to the detection liquid tube The path is connected, and the receiving component includes a spectrum receiving analyzer, which is arranged at the other end of the detection channel. The rapid microcystin content detector of the present invention is simple in structure, high in detection efficiency, wide in detection range, small in reagent consumption, has an integrated detection liquid preparation device, and is portable and portable.

Description

technical field [0001] The invention belongs to the technical field of detection instruments, in particular to a portable detection instrument for rapid detection of microcystins. Background technique [0002] Food is the material basis for the survival and development of human beings, and food safety is a major issue related to human health and national economy and people's livelihood. In recent years, frequent occurrence of malignant food poisoning incidents in some places and countries has attracted great attention from countries all over the world and relevant international organizations. Freshwater algae toxin is one of the factors affecting food safety. It is a metabolite produced by some algae living in freshwater. The food chain enters the human body, causing serious harm to human health. [0003] The problem of algal toxin pollution in food has attracted great attention and in-depth research all over the world. The monitoring and analysis of algal toxins in fresh w...

Problems solved by technology

[0004] Common algal toxin detection methods in the prior art, such as enzyme-linked immunosorbent assay, high performance liquid chromatography, liquid chromatography-mass spectrometry analysis, all require expensive detection instruments and complicated pretreatments, etc., and Since changes in instrument measurement conditions are closely related to test results, very professional analysis and test personnel are required to operate

Therefore, only the central laboratories of professional analysis and testing institutions and research institutions have the testing conditions, and the cycle of testing samples is relatively long, the testing process is complicated, the testing cost is high, and it is difficult to adapt to the environment and on-site spot checks of market products. Check the requirements for fast customs clearance for import and export of products
