ABSTRACT:
A method and apparatus are described for the determination of an analyte in an aqueous liquid while eliminating the biasing effect of unknown interferents which are preformed or formed in situ during the determination. The method comprises physically contacting a sample of the liquid with an interactive composition for the analyte; measuring the spectrophotometric responses generated by such contact at a primary wavelength .lambda..sub.1 and one or more secondary wavelengths .lambda..sub.2, .lambda..sub.3, . . . .lambda..sub.n ; and determining analyte concentration or activity using the equation:
