Abstract
This paper reports a method for the spectrofluorimetric identification of fourteen polycyclic aromatic hydrocarbons (PAHs) at the nanogram p er mililitre level in pure samples. The total fluorescence spectrum is scanned asynchronously to record the fluorescence intensity at 15 pre set excitation-emission wavelength pairs. By calculating a match index between the unknown sample and a library of standard samples, the fou rteen PAHs can be correctly identified. The match index obtained was a lways greater than 0.95.
