Abstract

Air samples of the atmospheric ground layer near the City of Ulm, Germany, in Central Europe and in the Southwest of the US including Salt Lake City, Utah, were analysed for organic nitrates. 43 alkyl mononitrates (C6-Ci3>, 24 alkyl dinitrates (Cj-Ce), 19 hydroxy alkyl nitrates (C:^), benzyl nitrate and 5 terpene nitrates have been identified. The analytical protocol included high-volume-sampling, NP-HPLC group separation, high resolution capillary gas chromatography, and the detection by the highly selective mass spectrometer detector (SIM mode, m
