Low Temperature Spectrofluorimetry of Complex Mixtures of PAH, Application to the Analysis of Isomeric PAH Extracted from Environmental Samples (Petroleum, Marine Sediments)

Abstract
Spectra obtained by High Resolution Spectrofluorimetry (HRS) in n-alkane matrices are more resolved and more structured than those obtained in nitrogen matrix. Analysis of petroleum and marine sediment fractions obtained by a two steps HPLC procedure allow us to identify and quantify the five isomers of the monomethylphenanthrene by HRS in n-hexane at 15K. Some results are compared with those obtained by GC-MS analysis.
