This paper discusses the figures of merit associated with the synchronous luminescence (SL) technique in multicomponent analysis of complex samples. Spectral interferences and experimental factors that influence the choice of experimental conditions are investigated. The efficacy of SL is demonstrated in the direct determination of anthracene and 2-methylanthracene in a raw coal liquid. The application of the second-derivative technique to the SL measurement of organic samples is shown. Special emphasis is directed toward the applicability of the SL technique as a practical and cost-effective screening procedure in the routine analysis of complex organic samples.

Synchronous Luminescence Spectroscopy

An analysis of coal liquids is demonstrated in the first application of the lifetime synchronous spectrum (LiSS) to the characterization of complex samples. The measurement of wavelength-resolved fluorescence lifetimes in the LiSS is shown to enhance the fingerprinting of coal liquids relative to conventional synchronous luminescence spectroscopy. The concentration independence of fluorescence lifetimes of individual compounds provides unique information about the composition of the coal liquids and the sources of their spectral features, indicating similarities among different samples and leading to the identification of regions in the synchronous spectra that are best for discriminating among the samples. The LiSSes also provided information about the nature of the processes responsible for spectral red shifts that occurred with increasing concentration of coal liquid.
