AB  - An analytical method was established for the simultaneous determination of 44 
      pesticide residues in ginger and scallion by ultra performance liquid 
      chromatography coupled with quadrupole-time of flight mass spectrometry 
      (UPLC-Q-TOF/MS). The samples were extracted with acetonitrile containing 0.1% 
      (v/v) acetic acid aqueous solution, and cleaned-up by primary secondary amine 
      (PSA) and octadecyl bonded silica (C(18)) adsorbents. The compounds were 
      separated on a Poroshell 120 SB-C(18) column (100 mmx3.0 mm, 2.7 mum) with 0.1% 
      (v/v) formic acid aqueous solution containing 5 mmol/L ammonium 
      acetate-acetonitrile as mobile phases under gradient elution. The eluent was 
      determined by UPLC-Q-TOF/MS with electrospray ionization in positive mode. The 
      quantification analysis was performed with the external standard method. In all 
      ions MS/MS mode, the compounds were qualitatively screened and confirmed by one 
      data acquisition. The correlation coefficients (r) were greater than 0.995 in the 
      linear ranges of the 44 pesticides. The limits of quantification (LOQs, S/N=10) 
      of the 44 pesticides were 2.5-5.0 mug/kg. At the three spiked levels, the 
      recoveries were between 73.4% and 113.7% with the relative standard deviations 
      (RSDs) ranging from 0.7% to 12.1% (n=6). The method effectively improves the 
      determination efficiency of pesticide residues screening by high-resolution mass 
      spectrometry.
