AB  - Objective: To establish a GDH-3 air sample tube for simultaneous determination of 
      twelve kinds of chlorobenzene compounds (CBs) in workplace air by gas 
      chromatography. And to established a matching determination method. Methods: In 
      October 2020, the vapor and aerosol CBs in workplace air were collected by GDH-3 
      air sampling tube, and desorption and elution with 3.00 ml toluene for 15 min, 
      then the solution separated by DB-23 capillary column, and finally detected with 
      microcell electron capture detector. Results: The quantitative determination 
      ranges of twelve isomers of CBs were 0.71x10(-3)-2000.00 mg/L, with the 
      correlative coefficients were 0.99967-0.99998. The minimum detectable 
      concentrations were 0.04-112.63 mug/m(3), and the minimum quantification 
      concentrations were 0.14-375.42 mug/m(3) (15.00 L sample, 3.00 ml sample solution) 
      . The average elution efficiencies were 96.00%-104.00%. The within-run relative 
      standard deviations (RSDs) were 2.54%-6.12%, and the between-run RSDs were 
      3.85%-7.87%. Sealed samples could be stable at room temperature for at least 15 
      days. Conclusion: GDH-3 air sample tube can be used for simultaneous 
      determination of twelve kinds of CBs in workplace air by gas chromatography. The 
      established supporting measurement method meets the measurement requirements of 
      the occupational health standard detection method, and the it's suitable for the 
      simultaneous determination of 12 kinds of CBS in the air.
