Popis: This paper describes the evaluation of a flow injection system with voltammetric multi-site detection, which enables the detector to carry out the measure of the sample at different positions in the manifold. Some advantages of these systems are partially discussed. A voltammetric cell with a tubular configuration and small inner volume (105 u.1) is proposed. This configuration has a very reduced effect on the hydrodynamic characteristics of the flow which makes it most attractive for manifolds with sequential detection. The manifold optimization was carried out using potassium hexacyanoferrate (II) in order to achieve a good separation of both analytical signals, a minimal sample dispersion and a high sampling rate.
