Electronic ID database and detection method for pesticide compound in edible agro-products based on LC-Q-Orbitrap
Disclosed is an electronic ID database and detection method for pesticide compound in edible agro-products based on LC-Q-Orbitrap. The electronic ID database includes a collection of various pesticides compound electronic ID information, intelligent matching values and collision energies. It is ordered according to the retention time in the electronic ID. The electronic ID contains pesticide compounds information, retention time, adduct ions information, fragment ions information, collision energies, and the optimal full scan mass spectrum. The detection method includes sample pre-treatment, setting LC-Q-Orbitrap operating conditions and sample pesticide residue screening. Setting LC-Q-Orbitrap operating conditions contain setting suitable chromatography and mass spectrometry conditions. In pesticide residue screening procedures, firstly, the retention time is used to find pesticide compounds electronic ID database. If matching, the corresponding electronic ID information is extracted. Then the intelligent matching value is compared, if it is same, the result is recorded and displayed, and the screening is completed.
