| 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%. CONCLUSION: The method is applicable to determination of 31 volatile organic compounds in the decorated rooms simultaneously" |
