| Abstract: | A rapid residue analysis method was developed for the determination of carbosulfan,carbofuran and 3-hydroxycarbofuran in wheat straw, soil and wheat grain by HPLC-MS/MS. The sample was extracted and cleaned up by d-SPE and determined by MRM mode based on isotope internal standard quantification. The LOQ for the three analytes in all the matrices was 5μg/kg,and the recoveries ranged between 73.3% and 98.6% with RSD 1.3% and 3.3%, which meet residue method requirement. |
