Simple unsegmented flow configurations for simultaneous kinetic determinations

Abstract Two unsegmented-flow manifolds were designed for simultaneous determinations based on differences in the kinetic behaviour of two analytes with the same reagent. The determination of Fe(III) and Co(II) based on displacement of Fe(III) and Co(II) from their EGTA complexes by PAR, was used as a model system. The displacement reactions were photometrically monitored at 510 nm.
