AB  - BACKGROUND: A needle trap device (NTD) was packed with Carbotrap/silica composite 
      sorbent and applied for field sampling of halogenated volatile organic compounds 
      (HVOCs) followed by gas chromatography/mass spectrometry (GC/MS) separation and 
      determination. METHODS: Carbotrap B, as a highly pure surface sorbent, was 
      prepared using sol-gel method to improve its surface properties for 
      adsorption/desorption of the target analytes. The effects of important 
      experimental variables on the sampling and determination of trichloroethylene 
      (thrCE) and tetrachloroethylene (tetCE) using the proposed NTD-GC/MS strategy 
      were evaluated and optimized. RESULTS: The results showed that sampling 
      temperature and relative humidity interfered with sampling efficiency of the 
      developed method and peak area responses of the analytes decreased with 
      increasing temperature and relative humidity. The peak areas of the analytes 
      increased with raising desorption temperature from 180 to 250  degrees C, and increasing 
      desorption time from 1 to 3 min. The carryover experiments showed that the 
      carryover effect disappeared after 3 min of desorption time. The Limits of 
      Detection (LODs) and Limits of Quantitation (LOQs) of the analytes were in the 
      range 0.01-0.03 and 0.05-0.09, respectively. CONCLUSIONS: The results indicated 
      that the developed NTD-GC/MS procedure can be used as a technology with high 
      sensitivity for the field sampling and determination of HVOCs.
