Lightning meets Mass Spectrometry Buchkatalog

In this work a quadrupole ion trap mass spectrometer was coupled to a smog chamber for in situ monitoring of degradation product formation of atmospherically relevant volatile organic compounds, in particular aromatic hydrocarbons. The focus was laid on the development of an adequate ionization stage, in particular on the design of a novel type of windowless operated spark discharge source for atmospheric pressure photoionization and on the design of a novel atmospheric pressure laser ionization source.
