Development and evaluation of innovative sampling, separation and ionization techniques for ultra-high resolution mass spectrometry: analysis of petroleum and combustion aerosol samples Rüger, Christopher Paul , 1990- (VerfasserIn) Zimmermann, Ralf , 1963- (GutachterIn) Jänis, Janne (GutachterIn) Karst, Uwe , 1965- (GutachterIn) Universität Rostock (Grad verleihende Institution) Universität Rostock Mathematisch-Naturwissenschaftliche Fakultät (Grad verleihende Institution) Text theses Text Hochschulschrift 2017 2017 eng electronic resourceremoteComputermedienOnline-Ressource1 Online-Ressource 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.<eng> vorgelegt von Christopher Paul Rüger Enthält Beiträge aus verschiedenen Zeitschriften Kumulative Dissertation Universität Rostock 2018 540 543 540 660 35.39 http://rosdok.uni-rostock.de/resolve/urn/urn:nbn:de:gbv:28-diss2018-0046-3 https://doi.org/10.18453/rosdok_id00002052 https://nbn-resolving.org/urn:nbn:de:gbv:28-diss2018-0046-3 https://d-nb.info/1293652008/34 Development and evaluation of innovative sampling, separation and ionization techniques for ultra-high resolution mass spectrometry--(DE-627)1017717850 urn:nbn:de:gbv:28-diss2018-0046-3 doi: 10.18453/rosdok_id00002052 oclc: 1031280186 ppn: (DE-627)1018609504
