Abstract: | The determination of volatile organic compounds in gypsum by thermal desorption with gas chromatography-mass spectrometry has been investigated. Mass spectrometry is used to qualitative analysis, and external comparison method is used to quantitative analysis. The detect hmit is 0.001mg/kg, and relative standard deviation (R.SD) is less than 5%. This method is low background, simple, rapid, and highly sensitive. |
