Analyzing the solid soot particulates formed in a fuel-rich flame by solvent-free MALDI FT ICR mass spectrometry.

CONCLUSIONS: The developed method provides a new approach for the molecular characterization of soot particulates like carbonaceous materials. The investigated soot particulates are mainly polycyclic aromatic hydrocarbons (PAHs) with no or very short aliphatic chains. The PAHs growth mechanism during combustion can be examined against the classic HACA mechanism.
