title: [A gas chromatographic method for determination of ethanol in workplace air].
abstract: OBJECTIVE
  To establish a gas chromatographic method for determination of ethanol in workplace air.
  
  
  METHODS
  Ethanol in the air was collected with silicone tube, desorbed with distilled water, separated with GDX-103 4 mm x 2 m stainless Steel packed column, and detected with flame ionization detector.
  
  
  RESULTS
  The penetrant capacity of silicone tube was 8 mg, the desorption efficiency was between 93.08% and 106.08%. The linear range of the method was from 13.0 to 6182.0 microg/ml, the correlation coefficient was 0.9999, the relative standard deviation (RSD) varied from 1.2% to 4.4%, and the detection limit was 1.7 mg/m3.
  
  
  CONCLUSIONS
  This method is feasible for the determination of ethanol in the workplace air.
