説明

Characterization of polycyclic aromatic hydrocarbons (PAHs) and fused-ring heterocyclic compounds (FHCs) in coal tar pitch, ranging from C12to C45, were performed by the combination of mass spectrometric methods. Semi-volatile PAHs and FHCs were analysed by GC/MS method. Non-volatile, heavier PAHs and FHCs up to C45, in coal tar pitch were analysed by liquid ionization (LI) MS by detecting their MH+ions.<BR>The addition of methanol to the ion source of LI-MS was effective to distinguish between PAHs and FHCs. Most of LI-MS spectral peaks were identified by the molecular map constructed based on the regularity of the increment of molecular weights to be observed by adding 6 membered rings to the known PAHs and FHCs.<BR>The above method was applied to the analysis of airborne total suspended particle, and could detect peaks corresponding to PAHs and FHCs, phthalic acid esters, fatty acid esters, fatty acids, and pesticide up to C37by the LI-MS.
