AB  - An analytical method for the determination of 34 pesticide residues in 
      plant-derived foods was established using an automated QuEChERS sample 
      preparation system combined with high performance liquid chromatography-tandem 
      mass spectrometry (HPLC-MS/MS). The sample extraction and dispersive solid-phase 
      extraction in the manual QuEChERS method were combined using the vortex vibration 
      and centrifugation functions of the automated QuEChERS sample preparation system. 
      The operating parameters and pretreatment steps were optimized, and the analytes 
      were detected in the multiple reaction monitoring (MRM) mode. The quantification 
      analysis was performed by the matrix-matched external standard method. The 
      automated and the manual QuEChERS methods were compared from the methodological 
      verification standpoint. The calibration curves showed good linearity in a 
      certain range, and the correlation coefficients (R(2)) were greater than 0.99. 
      The limits of detection and limits of quantification were 0.76-3.60 mug/kg and 
      2.28-10.80 mug/kg, respectively. Moreover, the recoveries ranged from 53.0% to 
      125.2%, and the relative standard deviations (RSDs) were less than 1.59% (n=5). 
      The results obtained by the manual QuEChERS method were not significantly 
      different from those obtained by the automated QuEChERS method. This method can 
      effectively reduce the labor intensity and probability of error in the 
      determination of pesticide residues.
