title: [Simultaneous determination of 31 volatile organic compounds in decorated rooms by two-stage thermal desorption-capillary gas chromatography].
abstract: OBJECTIVE
  To establish the monitoring method to simultaneously measure 31 volatile organic compounds in decorated rooms using two-stage thermal desorption-capillary gas chromatography.
  
  
  METHODS
  Using the Tenax TA absorption tube to sample, and subsequently desorbed and analyzed by two-stage thermal desorption capillary gas chromatography column, and measured by FID detector.
  
  
  RESULTS
  31 volatile organic compounds can be well separated in the chromatography column. In the experiment, the relative standard deviations of the reoccuring of each compound were within 10%. All the correlation coefficients of linear regression equation were greater than 0.99. The lowest detection limit can reach the concentration level of 1 ng/microl, and the recoveries were 83.2% - 106%.
  
  
  CONCLUSIONS
  The method is applicable to determination of 31 volatile organic compounds in the decorated rooms simultaneously.
