Description

Quick detection device of selenium content in selenium-rich agricultural product Technical Field The utility model relates to the technical field of detection equipment, in particular to a device for rapidly detecting the selenium content in selenium-enriched agricultural products. Background Selenium is a nonmetallic chemical element, belongs to an oxygen group element, plays an important role in nature, organisms and industry, proper intake of the selenium is important to maintain human health, and selenium-enriched agricultural products need to be detected by using detection equipment during production and processing. The existing selenium-enriched agricultural product selenium content detection equipment is mainly characterized in that the selenium-enriched agricultural product is diced when in use, then the diced agricultural product and a specific reagent are put into a test tube, the test tube is inserted into a detection bin of an organism, so that selenium reacts with the specific reagent to generate a fluorescent signal, the organism detects the fluorescent intensity, and the selenium content is quantified and measured through the fluorescent intensity.
