AB  - In this research, the manual two-step QuEChERS approach has been streamlined and 
      automated into a one-step method using a cleanup tube fitted within an extraction 
      tube. A novel automatic QuEChERS combination have been developed to simplify the 
      QuEChERS procedures and improve sample preparation efficiency. This combination 
      integrates QuEChERS procedures into a single run via the use of a vortex 
      vibration-centrifuge device and a centrifuge filtration tube. To validate the 
      efficiency of our automatic QuEChERS device, 270 pesticides were analyzed in 
      plant origined foods including celery, tomatoes, leeks, eggplants, grapes, corn, 
      green tea, and soybean oil using this automatic platform. The results were then 
      compared with those obtained using the manual QuEChERS method. Different 
      parameters were validated and compared including recovery, linearity, 
      repeatability and limits of quantification (LOQ). Satisfactory results, 
      comparable to results obtained using the manual QuEChERS method were obtained. 
      The average recoveries ranged between 70% and 120% for most pesticides with 
      associated relative standard deviations (RSDs) <20% (n=5) indicating satisfactory 
      accuracy and repeatability. An LOQ of 2mug/kg was obtained for most pesticides 
      present in celery and corn matrices, and the correlation coefficients (r(2)) were 
      >0.990 within a linearity range of 2-500mug/kg. Compared to manual QuEChERS, this 
      novel automatic QuEChERS device and combination could significantly improve the 
      sample preparation efficiency for the multiresidue analysis of pesticides.
