采用ＧＣ－ＭＳ特征质量离子分析方法同时测定相关样品中２０种德国禁用的偶氮染料芳香胺中间体物质。该法可同时进行定性和定量分析，定性分析具有快速、简便、可靠的特点，定量分析线性范围为（１０～１００）×１０－６，适合于禁用偶氮染料样品中目标芳香胺的ＧＣ－ＭＳ定性和定量分析。
Simultaneous determination of 20 German-banned azo-dyes aromatic amine intermediates in relevant samples by GC-MS characterization mass ion analysis. The method can be used for both qualitative and quantitative analysis. The qualitative analysis is fast, simple and reliable. The linear range of quantitative analysis is (10 ~ 100) × 10-6, which is suitable for banning the GC- MS qualitative and quantitative analysis.
