Abstract:
PMI (particulate matter index), correlating with increasing aromatics content, measures performance and environmental impact of fuels. While traditional aromatics measures using gas chromatography (GC) analyses are slow, challenged by co-elutions, and only quantitate on few individual isomers when there are many contributing species, this presentation explores using comprehensive two-dimensional gas chromatography (GCxGC) to resolve aromatics from other matrix interferences by creating separate, easy-to-interpret elution regions, providing more accurate quantitative information with simultaneous dual-detection from time-of-flight mass spectrometry and flame ionization detection to identify lower-level aromatic isomer species that influence PMI in one run that also returns area % based quantitation.
