Determination of nitrated polycyclic aromatic hydrocarbons in diesel particulates by gas chromatography with chemiluminescent detection
An analytical technique is described for the determination of nitrated polycyclic aromatic hydrocarbons (nitro-PAH) in diesel particulates. It involves the use of capillary gas chromatography for the separation of nitro-PAH and subsequent detection by chemiluminescence. The detection limit of the method is determined to 10-25 pg injected on-column. 1-Nitronaphthalene, 2-nitronaphthalene, 2-nitrofluorene, and 1-nitropyrene were selectively detected in the sample. The presence of 1-nitronaphthalene and 1-nitropyrene were unequivocally confirmed by mass spectrometry. Because of detector selectivity to nitro compounds, the presence of PAH and related derivatives does not interfere with the analysis. The technique is useful for the screening of nitroaromatics in complex environmental samples. 35 references, 3 figures, 2 tables.
