Abstract: A FIA system was described for studying the permeation, selectivity and dynamic properties of polymer films deposited on a glassy C disc electrode. The FIA system was equipped with a 500 µL injection loop and a thin-layer amperometric detector fitted with two glassy C electrodes (3 mm diameter), a Ag/AgCl (3 M NaCl) reference electrode and a steel auxiliary electrode. One of the glassy C electrodes was coated a polymer film, e.g., cellulose acetate, Nafion, polypyrrole, polyaniline or polyvinylpyridine. Several different test substances were injected into a 0.1 M phosphate buffer carrier stream of pH 7.4 and the responses obtained from the coated and uncoated working electrodes were compared. The advantages of the flow injection manifold are discussed; equations are derived to support the discussion.
