Rationale: Compound-specific stable isotope analysis (CSIA) has been performed as an advanced tool for assessing the sources and fates of various organic contaminates in environments. The use of gas chromatography - combustion - isotope ratio mass spectrometry (GC-C-IRMS) is constantly limited by the thermal stability, the polarity, and the occurrence of very low concentrations of the organic contaminates. Methods: However, the development of suitable derivatization for polarity organic contaminates can expand the application of GC-C-IRMS. With the goal of developing the nitrogen stable isotope analysis method of polarity organic amines in the atmosphere, a derivatization method was adopted. The method was evaluated for six aliphatic amines and three aromatic amines. Results: The derivatization method exhibited good reproductivity, high linearity, and no isotope fractionation. Accurate and precise nitrogen stable isotope measurements ( δ 15N) were obtained with derivatization. The deviation of δ 15N values from reference measurements by elemental analyzer - isotope ratio mass spectrometry (EA-IRMS) was small (˂ 0.33‰) and within the typical uncertainty for GC-C-IRMS (˂ 0.60‰). Method detection limits (MDLs) for nine organic amines were between 2.06 to 4.12 nmol N injected on column. Conclusions: The environmental applicability of the developed method was demonstrated for methylamine (MA). The δ 15N values of MA ranged from -11.55‰ to -9.12‰, -20.17‰ to -15.71‰, and -26.71‰ to -22.20‰ for vehicular exhaust, coastal, and municipal solid waste sanitary, respectively, indicating that the δ 15N values could well discriminate their sources.
