      through a Modified QuEChERS Method.

AB  - A rapid and simple analytical method for triflumezopyrim, a new class of 
      mesoionic insecticides and commercialized molecules from DuPont, was developed 
      with a modified QuEChERS method. The pH adjustment was used to improve the 
      extraction efficiency of acetonitrile solvent, and dispersive solid-phase 
      extraction was employed for the clean-up process. The five selected food 
      commodities were used to verify the present optimized method, which displayed 
      good linearity with an excellent correlation coefficient (R(2) = 0.9992-0.9998) 
      in the 0.003-0.30 mg/kg calibration range. The method limits of detection (LOD) 
      and quantification (LOQ) were determined to be a value of 0.003 and 0.01 mg/kg, 
      respectively. The mean recovery for the triflumezopyrim was in the 89.7-104.3% 
      range. The relative standard deviations were </=9.8% for intra- (n = 5) and 
      inter-day (n = 15) precisions at concentrations of 0.01, 0.1, and 0.5 mg/kg in 
      the five representative samples. The matrix effect has been calculated to confirm 
      the effect during ionization of the analyte in the UPLC-MS/MS. The matrix effects 
      of the instrumental analysis showed that triflumezopyrim was less susceptible to 
      matrices. The proposed analytical method in this study has effectively improved 
      the accuracy, selectivity, and sensitivity for the determination of 
      triflumezopyrim in agricultural commodities; therefore, it can serve as a 
      reference method for the establishment of maximum residue limits (MRLs).
