      liquid chromatography-tandem mass spectrometry].
PG  - 1070-5
AB  - An ultra performance liquid chromatography-tandem mass spectrometric method 
      (UPLC-MS/MS) was established for the simultaneous determination of imidacloprid, 
      carbendazim, thiophanate-methyl, propamocarb, methomyl and dimethomorph residues 
      in tomato paste. The samples were extracted by methanol-water (1: 1, v/v) 
      containing 0.1% (v/v) acetic acid. The separation was performed on a Waters 
      Acquity UPLC system with a BEH C18 column with the gradient elution of methanol 
      and water (containing 10 mmol/L ammonium acetate). The six pesticides were 
      determined in the modes of electrospray positive ionization (ESI+) and multiple 
      reaction monitoring (MRM). The analytes were quantified by matrix-matched 
      standard solution, and the calibration curves showed good linearity within the 
      concentrations of 0.005 to 0.2 mg/L and the correlation coefficients (r) were 
      more than 0.995. The average recoveries of the six pesticides ranged from 66.8% 
      to 102.9% in the three spiked levels of 0.02, 0.05 and 0.2 mg/kg. The relative 
      standard deviations (RSDs) were all less than 15%. The limits of quantification 
      (LOQ, S/N > 10) were 0.02 mg/kg for the all analytes. The results indicate that 
      the method is easier, faster, more sensitive, and suitable for the qualitative 
      and quantitative confirmation of the six pesticide residues from tomato paste.
