Brief description on the applications of Thin Film Electrodes

Veronica Lodge

ASV is a powerful electrochemical analytical approach for detecting and measuring a wide spectrum of metal ion species in aqueous fluids at extremely low concentrations. While early ASV tests relied on macroscopic electrodes such Hg drop electrodes to provide plating/stripping-ready surfaces, more recent work on the approach has relied on thin film metal electrodes made in situ to replace these electrodes. Such electrodes are plated with the analyte species onto the surface of a primary electrode, resulting in a composite metal electrode from which the analyte(s) may be extracted, identified, and quantified.
