      chromatography using back-flush technique].
PG  - 724-8
AB  - The back-flush technique was used in the determination of organophosphorus 
      pesticide residues in vegetables by gas chromatography. The pesticide residues 
      were extracted with acetonitrile and sodium chloride under mechanical shaking, 
      and separated by centrifuging and partitioning. The extract was analyzed by gas 
      chromatograph equipped with a flame photometric detector and a micro fluidic 
      device with back-flush function. The results showed that the 16 organophosphorus 
      pesticides have good linearity within the concentration range of 0.040 -3.20 
      mg/L. The recoveries varied from 75.2% to 111.5%, with the relative standard 
      deviations (RSDs) in the range of 2.8% - 10.4%. The detection limits of these 
      target compounds were from 0.003 to 0.01 mg/kg. The application of back-flush 
      technique in this method significantly reduced the cycle time and matrix effect 
      and improved the analysis efficiency.
