Applications of multidimensional absorption and luminescence spectroscopies in analytical chemistry

Analysis of Olive Oils by Fluorescence Spectroscopy: Methods and Applications

“…Total luminescence spectra are usually obtained by measurement of emission spectra at several excitation wavelengths. They may be presented as a three dimensional plot, with the fluorescence intensity plotted in function of the excitation and the emission wavelengths (Ndou and Warner, 1991;Guilbault, 1999). Another representation of the total luminescence is obtained using two-dimensional contour maps, in which one axis represents the emission and another -the excitation wavelength, and the contours are plotted by linking points of equal fluorescence intensity, Fig.1.…”

Fluorescence spectroscopy in monitoring of extra virgin olive oil during storage

“…In such cases, total luminescence or synchronous scanning fluorescence (SSF) techniques are applied, improving the analytic potential of the fluorescence (Gutierrez et al. , 1987; Ndou & Warner, 1991; Patra & Mishra, 2002).…”

Applications and New Developments in Fluorescence Spectroscopic Techniques for the Analysis of Polycyclic Aromatic Hydrocarbons

“…In last two decades, extensive research is continuing on the use of molecular fluorescence as analytical techniques in the analysis of PAHs, and few of them are reviewed in 1982 independently by Warner and McGown [1] and by Futoma et al [2] and in 1991 by Ndou and Warner. [3] Santana Rodriguez and Padron Sanz [4] have reviewed PAHs analysis in the marine environment. PAHs are also known as polynuclear aromatic hydrocarbons or polyarenes and constitute a large class of organic compounds.…”
