AB  - A method of comprehensive screening of the target and non-target volatile organic 
      compounds (VOCs) in industrial exhaust gas using thermal desorption-gas 
      chromatography-mass spectrometry (TD-GC-MS) has been developed. In this paper, 
      two types of solid phase adsorption column were compared, and the Tenex SS TD 
      Tube was selected. The analytes were enriched into the adsorption tube by 
      constant flow sampling, and detected by TD-GC-MS in full scan mode. Target 
      compounds were quantified by internal standard method, and the quantities of 
      non-target compounds were calculated by response coefficient of toluene. The 
      method detection limits (MDLs) for the 24 VOCs were 1.06 to 5.44 ng, and MDLs 
      could also be expressed as 0.004 to 0.018 mg/m(3) assuming that the sampling 
      volume was 300 mL. The average recoveries were in the range of 78.4% to 89.4% 
      with the relative standard deviations (RSDs) of 3.9% to 14.4% (n=7). The 
      established analytical method was applied for the comprehensive screening of VOCs 
      in a waste incineration power plant in Dalian city. Twenty-nine VOCs were 
      identified. In these compounds, only five VOCs were the target compounds set in 
      advance, which accounted for 26.7% of the total VOCs identified. Therefore, this 
      study further proved the importance of screening non-target compounds in the 
      analysis of VOCs in industrial exhaust gas, and has certain reference 
      significance for the complete determination of VOCs distribution.
