Abstract

A gas chromatography-mass spectrometry (GC-MS) analytical protocol for quantitation of PAHs in diesel exhaust particles, adapted for a single laboratory period, is proposed. Gravitational chromatography is first used to isolate aromatic compounds. Then quantitative determination of PAHs (polycyclic aromatic hydrocarbons) is performed by GC-MS, using deuterated PAHs as internal standards. Results obtained by students for recovery yields and for quantitation are reproducible.
