Fig. 4. (A) Overlapped experimental chromatograms obtained with FLD at λem = 330 nm for the studied system under the selected working conditions (top), and the normalized
fluorescence spectra in the first (medium) and second (bottom) evaluated time regions. The arrow in the chromatogram marks the excitation wavelength change (see text).
(B) Profiles retrieved by MCR-ALS for the same system.
