Development and evaluation of innovative sampling, separation and ionization techniques for ultra-high resolution mass spectrometry : analysis of petroleum and combustion aerosol samples

Universität Rostock, 2018

Abstract: Novel approaches for the analysis of complex mixtures by high-resolution mass spectrometry are shown. A laser desorption/ionisation method for combustion particles was developed, whereas in electrospray ionisation a new dopant was introduced. For gas chromatography automatised algorithms providing more reliable data were developed. Coupling to thermal analysis enlarged the detectable species. This approach is evaluated for various complex mixtures, such as petrochemicals and biomass. Finally, a detailed chemical description of the most complex crude oil fraction, asphaltenes, could be shown.
