Simultaneous Determination of Polycyclic Aromatic Hydrocarbons by Variable Angle Spectrofluorimetry

Abstract
The use of variable-angle fluorescence spectra together with multilinear curve-fitting techniques for the resolution of mixtures of polycyclic aromatic hydrocarbons (PAHs), is described. Only one spectrum is necessary to determine four compounds in a mixture even when a severe overlap occurs. The PAHs are quantified at ng/ml levels.
