An integrated approach comprising a combination of glass capillary gas chromatography (GC), mass spectrometry (MS), liquid chromatography (LC), and ultraviolet (UV) spectrometry has been used for unambiguous identification of polynuclear aromatic hydrocarbons (PAH) in airborne particulates. Liquid chromatography with on-line ultraviolet spectral scanning was particularly valuable for differentiation and positive identification of isomeric and coeluting PAHs. The advantages of this approach over GC/MS alone are illustrated. Parent PAHs containing three to seven rings were found in most samples examined, some alkyl- and alkoxy-PAHs were also detected. A simple, one-step procedure for isolation of PAHs by preparative thin-layer chromatography is also reported.
