Determination of 51 Pesticide Residues in Cereals Using Accelerated Solvent Extraction and Gas Chromatography-Triple Quadrupole-Tandem Mass Spectrometry
A method was developed for detecting 51 pesticide residues in import and export cereals by gas chromatographytriple quadrupole-tandem mass spectrometry(GC-MS/MS). The optimal conditions for accelerated solvent extraction were established by investigating the effect of extraction temperature and solvent on extraction efficiency. The purification efficiencies of three different methods were compared for pesticide residues extracted from sorghum and barley. Multipesticide residues in sorghum were detected by G...
