Electronic ID database and detection method for pesticide compounds in edible Agro-products based on GC-Q-Orbitrap
Disclosed is an electronic ID database and detection method for pesticide compounds in edible agro-products based on GC-Q-Orbitrap. The electronic ID database includes a collection of various pesticide compounds electronic ID information and is sorted according to retention time in the electronic ID. The electronic ID contains pesticide compounds information, retention time, mass spectrum, fragment ions information and intelligent matching value. The detection method includes sample pretreatment procedures, setting GC-Q-Orbitrap operating conditions and screening procedures for pesticide residues in samples, wherein setting GC-Q-Orbitrap operating conditions includes setting suitable chromatography and mass spectrometry conditions. In pesticide residue screening procedures, firstly, the retention time is used to find out pesticide compounds in electronic ID database. If there is a match, the corresponding electronic ID information is extracted. Then the intelligent matching value is compared, if it is less than threshold value, the result is recorded and displayed, and the screening is completed.
