Die chemische Analyse von schweren Fraktionen und Polymeren bereitet Probleme. Die
Thermische Analyse mit nachfolgender Photoionisierungsmassenspektrometrie ist hingegen
gut geeignet, um diese anspruchsvollen Proben zu untersuchen. Komponenten werden verdampft
oder durch Pyrolyse in kleinere Bruchstücke zersetzt, die dann mittels weicher, universeller
oder selektiver Photoionisierung ionisiert und massenspektrometrisch detektiert werden.
Neben der Evaluation der Methode, konnten so neue Erkenntnisse über Asphaltene, Foulingproben,
Polyethylen und Polyethylenterephthalat gewonnen werden.

Chemical analysis of heavy, highly viscous and poorly soluble fractions is still problematic.
However, thermal analysis hyphenated to photo ionisation mass spectrometry is well
suited for these challenging samples. Components either evaporate, or decompose into
smaller products, which are then ionised by soft, universal or selective photo ionisation
and detected by subsequent mass spectrometry. Besides the evaluation of the employed
technique, new findings about asphaltenes, fouling samples, the branching of polyethylene
and decomposition of polyethylene terephthalate are presented.
