AB  - A method is presented for the determination of difenoconazole residue in all 
      kinds of foods by solid phase extraction-gas chromatography-negative chemical 
      ionization mass spectrometry (SPE-GC-MS/NCI). Difenoconazole residue was 
      extracted with ethyl acetate from different samples, such as perilla leaves, 
      carrots, spinach powder, rice, gram, jasmine flower tea, oolong tea, 
      strawberries, sauce, bee honey, beef, chicken and eels, etc. The extracts were 
      cleaned-up by active carbon SPE column connected to alumina neutral SPE column or 
      Florisil SPE column only. Analytical screening was determined by the technique of 
      GC-MS/NCI on selected ion monitoring mode. The recoveries of difenoconazole in 
      most samples were in the range from 70% to 120% at three spiked levels, 0.01 
      mg/kg, 0.04 mg/kg and 0.10 mg/kg, and the relative standard deviations (RSDs) 
      were below 9.5%. The linearity of the method is good from 0.02 to 1.00 mg/L, and 
      limit of detection (LOD) was 0.000 5 or 0.001 mg/kg for different type samples. 
      The method is selective without interference and is suitable for determination 
      and conformation of difenoconazole residue in all kinds of foods.
