摘要
采用气相色谱 -质谱分析甲苯二异氰酸酯 (TDI) ,以TDI80为例 ,对测试过程中样品的存放、溶剂及色谱条件的选择、组分定量作了探讨 ,获得满意的结果。该法无需标样 ,具有定性定量准确。
Gas chromatography-mass spectrometry was used for the analysis of toluene diisocyanate(TDI). Take TDI 80 for example, effect of sampling and solvent, and chromatographic conditions were discussed. TDI isomers were qualitatively analyzed by GC-MS and quantitatively analyzed by GC with normalization method of areas. The method is simple, accurate and does not need standard.
