title = "Resolving thermal mass loss of diesel particulate matter by the identification of aromatic carboxylic acids and anhydrides",
abstract = "Conventional methodology for the determination of organic compounds condensed on diesel particulate matter (PM) is solvent extraction followed by gas chromatography/flame ionization or gas chromatography/ mass spectrometry (GC/MS) analysis. The calculated mass of the extracted compounds does not often correspond to the total mass of thermally desorbed compounds from diesel PM. Recently, our laboratory identified a family of aromatic carboxylic acids and anhydrides on diesel PM. Conventional GC/MS analysis revealed very poor sensitivity for these compounds, thus indicating a potentially large abundance of the compounds on PM. We report on the presence of these compounds in PM and the use of liquid chromatography/mass spectrometry for the determination and the quantification of pyromellitic acid and similar aromatic compounds on diesel PM. The identification and quantification of this family of compounds may be valuable in the understanding of the combustion mechanism, PM formation and possible heath impacts.",
