摘要: Despite the fact that a significant number of organic and inorganic compounds have been measured in aerosol samples, relatively little is known about nitrogen (ON) content. The ON components 23 urban samples were characterized using direct thermal desorption technique (DTD) together with comprehensive two-dimensional gas chromatography-time flight mass spectrometry (GCxGC-TOF/MS). Between 17 57 various mainly nitriles, amides, amines, nitro found individual collected on different dates from same location. In total identifications made for over 100 aerosol. Aminomethanesulfonic acid, o-cyanobenzoic acid hexadecanenitrile all samples. 4-[2-(methylamino)ethyl]-phenol, pyridine, 4,4a,5,7a-tetrahydro-8,8-dimethyl-(1a,4a, 4aa,7aa)-1,4-methano-1H-cyclopenta[d]pyridazine, caprolactam, tetradecanitrile, penoxaline, tetradecanamide, eicosanenitrile detected many sa...
