摘要
本文采用热解析-气相色谱质谱联用法对石膏板中的挥发性有机化合物进行测定。本方法以质谱定性,外标法定量,最低检出限为0.001mg/kg,相对标准偏差小于5%。该方法本底低,操作简单,快捷,灵敏度高。
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.
