| Abstract | Recent advances in the field of laser desorption/laser ionization mass spectrometry (LD/LI/MS) have renewed interest in these separation methods for fast analysis of chemical species adsorbed on soot particles. These techniques provide mass-separation of the desorbed phase with high selectivity and sensitivity and require very small amounts of soot to be collected. In particular the techniques provide a means to measure adsorbed polycyclic aromatic hydrocarbons (PAHs). PAHs are important precursors of carbonaceous soot particles, thus influence the quantity and morphology of particulate emission from various combustion processes. Furthermore, PAHs absorbed on the surface of the soot particles contribute to the carcinogenicity of the particles. Therefore, there is scientific interest in characterizing and quantifying these adsorbed PAHs in order to provide key information about the mechanism of the soot formation for various fuels and combustors and to understand their health impact. This has motivated various studies; however, an extensive characterization of the PAHs absorbed onto soot particles remains a challenge. |
