Nitrogen Isotope Analysis of Aliphatic and Aromatic Amines by GC‐C‐IRMS and the Application for Tracing Atmospheric Organic Amine Sources
The applicability of the developed method was demonstrated through analysis of atmospheric methylamine (MA). The measured δ<sup>15</sup>N values of MA varied significantly across sources, ranging from -11.6‰ to -9.1‰ for vehicular exhaust, -20.2‰ to -15.7‰ for coastal samples, and -26.7‰ to -22.2‰ for municipal solid waste sanitary sources, indicating that δ<sup>15</sup>N values effectively distinguish MA sources.
