Abstract
A novel measuring procedure is proposed for flow-injection analysis. F ast, multiple injection of the same standard or sample solution and Fo urier transform of a measured periodic signal allows to obtain a respo nse linearly related to concentration with improved signal-to-noise ra tio. The effectiveness of the proposed procedure was demonstrated for the flow-injection determination of nitrite with biamperometric detect ion.
