Abstract

Attempts have been made to determine two analytes simultaneously using one optical indicator. Two approaches were pursued: The first is based on multi-wavelength amplitude analysis of the fluorescence excitation or emission spectrum and the second on amplitude/lifetime analysis of the emission spectrum of a single indicator. Both methods are suitable for determination of two species if one affects the electronic ground state and the other the excited state.
