| Abstract: | An LC-QqQ-MS-MS(liquid chromatography tandem triple quadrupole mass spectrometry) method for determination of clethodim was developed. The mobile phase was acetonitrile-water-formic acid(90:10:0.1, by vol) and the clethodim residues in rape and soil were detected in multiple reaction mode(MRM). The results showed that, when the fortified level were 0.01, 0.05, 0.10 mg/kg, the recoveries were in the range of 90-100% and the relative standard deviation(RSD) were less than 10%. |
