摘要
Abstract
[Objective] To establish a rapid qualitative method for detecting dichlorvos and omethoate in biomaterials.[Methods] Dichlorvos and omethoate in gastric juice and blood samples were extracted by dichloromethane and evaporated using nitrogen stream.The residues were dissolved with dichloromethane and detected by gas chromatography-mass spectrometry (GC/MS).Indicators of sample pre-treatments and GC/MS conditions were described.[Results] The detection of dichlorvos and omethoate in biomaterials could be finished in 60min.A qualitative conclusion was drawn by comparing the total ion chromatograms and the mass spectrums of the samples with the standard mass spectra.[Conclusion] The method can rapidly and accurately identify dichlorvos and omethoate in gastric juice and blood samples.关键词
