本文件规定了使用逸出气体分析/气相色谱-质谱（EGA/GCMS）对单壁碳纳米管（SWCNT）样品中逸出气体成分进行表征的方法。 注:由于加热和催化剂的可能存在，排放气体和样品中气体含量的定性和定量结果可能会出现一些差异。

This document specifies a method for the characterization of evolved gas components in single-wall carbon nanotube (SWCNT) samples using evolved gas analysis/gas chromatograph mass spectrometry (EGA/GCMS). NOTE Some difference could appear between qualitative and quantitative results of emitted gas and gas content in the sample due to the heating and the possible presence of catalysts.
