Abstract: 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.
