Real-Time Measurements of Nitrogen-Containing Organic Compounds Emitted From Diesel Vehicle Exhaust

Proton transfer reaction-mass spectrometry (PTR-MS) allows highly time-resolved measurements of multiple volatile organic compounds (VOCs) at trace levels in air. The measurement of VOCs, especially nitrogen-containing organic compounds emitted from diesel vehicle exhaust was performed by PTR-MS. Emissions of nitromethane, nitrophenol, and acetonitrile from the diesel vehicle exhaust were observed in addition to aromatics and oxygenated VOCs. It was found that the emission of nitromethane is strongly correlated with those of CO, benzene, and acetone while that of nitrophenol is correlated with those of acetonitrile, acetic acid, and phenol.
