Abstract

Nine brands and grades of gasoline were analyzed by three dimensional fluorescence spectroscopy (3-DF). Capillary gas chromatograms were also obtained in order to monitor the loss of components during evaporation. All samples were examined neat, then after 50% evaporation, and then after evaporation until only a semi-solid residue remained (nearly evaporated). It was found that the fluorescence technique was capable of distinguishing among the samples in both neat and evaporated conditions and that it showed similarities between neat and 50% evaporated samples. The totally evaporated samples could not be associated with its corresponding neat sample.
