Abstract

The concepts underlying the definition and calculation of fundamental influence coefficients and their role in the computation of derived coefficients in alpha-type algorithms are examined. The fundamental-parameter method initiated and continues to provide the basis for the steady progress in giving influence coefficients a sound theoretical status. New definitions of fundamental influence coefficients as the prorating of monochromatic coefficients on the basis of the intensities of each elementary contributions as a function of the total fluorescence intensity and of the intensity of the pure analyte are compared to the presently used approach of defining coefficients as a function of total absorption only.
