A successful qualitative and quantitative analysis of polycyclic aromatic hydrocarbons (PAHs) in air-borne particulates in Hong Kong City has been carried out by the heuristic evolving latent projection (HELP) method recently developed in chemometrics. The resolution result showed that 47 compounds were involved in this sample. Eighteen of them were interesting PAHs and/or their derivatives. The result agreed very well with the one obtained by capillary column GGMS. The resolved UV-visible spectra match well with the standards. With the help of HELP method, accurate quantitative results were also obtained for all the overlapping peaks. The separation ability of chromatography is greatly enhanced by chemometric methods. The HELP method provides a completely new way for quick and accurate analysis of the two-dimensional data produced by hyphenated chromatographic instruments.
