TI  - [Determination of 61 organophosphorous pesticide residues in fruits, vegetables, 
      milk, vegetable oils and animal muscles by dispersive solid-phase extraction and 
      ultra performance liquid chromatography-tandem mass spectrometry].
PG  - 618-23
AB  - A dispersive solid-phase extraction coupled with ultra performance liquid 
      chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed for the 
      determination of 61 organophosphorous pesticide residues in fruits, vegetables, 
      milk, vegetable oils and animal muscles. The fruit, vegetable and milk samples 
      were extracted with acetonitrile and separated with salting out method; vegetable 
      oil samples were dissolved by n-hexane, and extracted with acetonitrile; animal 
      muscle samples were extracted with acetonitrile-water assisted by n-hexane and 
      separated with salting out method. And then the supernatants were purified using 
      dispersive solid-phase extraction (C18 and primary secondary amine powder) prior 
      to the UPLC-MS/MS analysis. The analytes were indentified in positive 
      electrospray ionization (ESI+) and multiple reaction monitoring (MRM) mode. The 
      matrix-matched external standard calibration curves were used for quantitative 
      analysis. Under the optimal conditions, the detection limits (S/N > or = 10) of 
      the method were 0.01 mg/kg. The recoveries were 62.8%-107%, and the relative 
      standard deviations (RSDs) were in the range of 4.2%-19%. The method has the 
      advantages of easy, fast, and more sensitive, and can meet the requirement of the 
      determination of organophosphorous pesticide residues in the foods.
