摘要：

Spectral resolution of two-component systems by multiway analysis of excltation-emission-frequency arrays is compared with single-matrix analysis of steady-state excitation-emission matrices for both real and computer-simulated systems. Fluorescence lifetime selectivity can improve resolution, especially for the minor component In mixtures in which the two components have unequal contributions to the total intensity. However, In some cases the lifetime difference between two fluorophores is insufficient to aid resolution. © 1990, American Chemical Society. All rights reserved.
