Identification and Quantitation of Polycyclic Aromatic Compounds in Air Particulate and Diesel Exhaust Particulate Extracts by LC--GC

Abstract

Particulate matter collected from the atmosphere and from diesel engine exhaust was analyzed using on-line LC—GC for polycyclic aromatic compounds. An on-column interface was used, and quantitation was achieved through the addition of an extra valve to the system. The results obtained are discussed with respect to the sample origin.
