ELECTRONIC METHOD FOR NON-TARGETED, MULTI-INDEX AND RAPID DETECTION OF PESTICIDE RESIDUE IN EDIBLE AGRICULTURAL PRODUCTS

摘要

An electronic method for non-targeted, multi-index and rapid detection of pesticide residue in edible agricultural products, comprising the steps; first: establishing a first-level accurate mass spectrometry database and a second-level fragment ion mass spectrometry database of more than 1200 pesticides commonly used worldwide; using the two mass spectrometry databases for screening and confirmation of a pesticide compound, and establishing a unique electronic identity card for each pesticide, such that a standard of a conventional identification method using a physical pesticide as a reference is replaced with an electronic standard; second: developing software for high-resolution mass spectrometry based automatic matching, qualitative identification, and intelligent screening of pesticide residues, and embedding a software program into an instrument, such that comparison between test samples and pesticide mass spectrometry databases is rapid, throughput and accuracy are high, data is reliable, and processes are informationized and automated; and third, preparing a sample once, and using two detection techniques to simultaneously check for more than 1200 pesticides. The invention realizes multi-index, non-targeted, and rapid detection of pesticide residues in edible agricultural products, greatly improving detection efficiency.
