GC-Q-ORBITRAP-BASED ELECTRONIC IDENTIFICATION DATABASE OF PESTICIDE COMPOUNDS IN EDIBLE AGRICULTURAL PRODUCTS AND DETECTION METHOD

摘要

A GC-Q-Orbitrap-based electronic identification database of pesticide compounds in edible agricultural products and a detection method; the electronic identification database comprises the assembling of electronic identity card information of a plurality of pesticide compounds, and sorting according to the retention times in the electronic identity card, wherein the electronic identity card comprises pesticide compound information, retention time, a mass spectrograph, fragment ion information and a smart matching value; the detection method comprises a sample pretreatment step, the setting of GC-Q-Orbitrap operation conditions, and a pesticide residue screening process in the sample, wherein the setting of GC-Q-Orbitrap operation conditions comprises setting a suitable chromatographic condition and mass spectrometry condition and, in a pesticide screening process, first utilizing the retention time to search for a pesticide compound in the electronic identification database, and extracting corresponding electronic identity card information if matching is successful, then comparing a smart matching value, and recording and displaying a result if the smart matching value is less than a threshold, and screening is thus finished.
