ABSTRACT:
A method for on-line analysis of polycyclic aromatic hydrocarbons (PAH) in aerosols. The aerosols are collected on non-fluorescing filter paper, excited to fluorescence and imaged spectrally. The images are compared with spectra in a database to determine and quantify the PAH species present. The scope of the invention is broader than fluorescence, and includes excitation analysis of particulate matter generally.
