An Analytical Approach for a Comprehensive Study of Organic Aerosols The financial support by the Bundesministerium für Bildung und Forschung and the Senatsverwaltung für Wissenschaft, Forschung und Kultur des Landes Berlin (ISAS Berlin), and the Ministerium für Schule, Wissenschaft und Forschung NRW (ISAS Dortmund) is gratefully acknowledged. The authors want to thank U. Marggraff and W. Nigge (Dortmund) for assistence during MS measurements and Dr. R. Köppe (Univ. Karlsruhe) and Dr. H. Sievers (GSG Karlsruhe) for assistance in FT-ICR-MS measurements.
Unknown products identified precisely: The coupling of liquid chromatography to NMR spectroscopy, mass spectrometry, and infrared spectroscopy and the use of high-resolution mass spectrometry is utilized to investigate the formation of atmospheric-relevant organic aerosols. The investigation focussed on the gas-phase reaction of α-pinene with ozone and the subsequent identification of the reaction products by the coupled analytical techniques.
