- Abstract
- Advanced mass spectrometric systems have been tested for the analysis of heavy fractions of
fuel oils and combustion-formed particulate in terms of mass range detection and resolution.
The analysis of these complex aromatic samples is not amenable to conventional chromatographic-
mass spectrometric techniques due to their low volatility and degradability. In this
paper, the advantages and the shortcomings of different ionization methods (electron
impact, photoionization, laser ionization) and different mass analyzers (quadrupole, ion
trap, time of flight) have been carefully investigated. The optimization of operative parameters
has shown to be crucial for the extension of mass detection range. The Atmospheric
Pressure Photoionization-Mass Spectrometry techniques showed the best performances in
terms of low fragmentation of the parent ion and sensitivity for the analysis of asphaltenes.
Laser Desorption Ionization-Mass Spectrometry showed to be more suitable for the analysis
of aromatic tarry combustion-formed species. (literal)
