      phase extraction coupled with gas chromatography-mass spectrometry].

AB  - The short chain chlorinated paraffins (SCCPs) are the additives frequently used 
      in the leather production in China, but they have been put into the list of 
      forbidden chemicals issued by European Union recently. In fact, there is not a 
      commonly recognized method for the determination of the SCCPs in the leather 
      products due to the serious matrix interferences from the leather products and 
      the complex chemical structures of the SCCPs. A method of solid phase extraction 
      coupled with gas chromatography-mass spectrometry (SPE-GC-MS) was established for 
      the determination of the SCCPs in the leather products after the optimization of 
      the SPE conditions. It was found that the interferences from the leather products 
      were thor- oughly separated from the analyte of the SCCPs on a home-made solid 
      phase extraction (SPE) column filled with silica packing while eluted with a 
      mixed solvent of n-hexane-methylene chloride (2:1, v/v). With this method, the 
      recoveries for the SCCPs spiked in the real leather samples varied from 90.47% to 
      99.00% with the relative standard deviations (RSDs) less than 6.7%, and the 
      limits of detection (LODs) were between 0.069 and 0.110 mg/kg. This method is 
      suitable for qualitative and quantitative analysis of SCCPs in the leather 
      products.
