Title: Quantitation of nitro- and dinitropolycyclic aromatic hydrocarbons in diesel exhaust particulate matter

Journal Article · · Chemosphere; (United States)
OSTI ID:7172640

A method for routine trace analysis of nitropolycyclic aromatic hydrocarbons (nitro-PAH) in diesel exhaust particulate matter is described. Particle extracts are prefractionated by silica high pressure liquid chromatography and the appropriate band analyzed by capillary electron capture gas chromatography. With on-column injection, three dinitropyrene isomers were recovered in the range of 69-85% for fortifications of 10 ..mu..g nitro-PAH/g of soot. The high signal-to-noise ratio suggested detection limits of about 2 ..mu..g/g for these analytes. Analysis of the Bureau of Standards SRM 1650 diesel particulate sample demonstrated the methods accuracy for 1-nitropyrene determinations as well.
