HPLC-MS/MS Determination of Flucarbazone-sodium and Its Metabolites Residue in Wheat Grain, Straw and Soils

Abstract: An analytical method was developed to measure the residues of Flucarbazone-sodium and its Metabolites in wheat grain, straw, and soil by HPLC-MS/MS. The lowest level of method validation (LLMV) is 0.01 mg•kg^－1 for Flucarbazone-sodium and its Metabolites in straw and soil, and 0.005 mg•kg^－1 in wheat grain. The average fortified recoveries are between 74% and 103% with a relative standard deviation (RSD) between 3.4% and 16.3%.
