Resumo: A flow-injection (FIA) manifold is described for the simultaneous determination of potassium and sodium in samples of vegetables using flame emission spectrometry as the detection process. Two dialysis units were included so as to provide the system with a high dilution capacity (dilutions of about 600 - 700 fold), and also to allow bicomponent analysis: the same sample plug was divided between a donor and an acceptor stream that were subsequently directed to two detectors placed in parallel. The results of the FIA method were in good agreement with those of the reference procedures (relative deviations lower than 3%). Sampling rates from 120 to 150 samples per hour (corresponding to 240 to 300 determinations per hour) were achieved with relative standard deviations below 1.7%.
