Liquid chromatographic determination of polycyclic aromatic hydrocarbons in air particulate extracts
Reversed-phase liquid chromatography (LC) with fluorescence detection was used for the determination of 13 polycyclic aromatic hydrocarbons (PAH) in urban air particulate material as part of the process of certifying this material as Standard Reference Material (SRM) 1649. The fluorescence excitation and emission wavelengths were changed during the chromatographic analysis to optimize the selectivity for individual PAH. A second approach was employed which involves normal-phase LC on an aminosaline phase to isolate PAH fractions based on the number of aromatic carbons, followed by analysis of these fractions by reversed-phase LC with UV or fluorescence detection. Results obtained by use of the LC methods are compared with results obtained by gas chromatography. Analytical results obtained by using these LC methods are presented for the analysis of a second urban particulate material (SRM 1648) and a diesel exhaust particulate sample. 38 references, 4 figures, 5 tables.
