Anodic stripping voltammetry is an important technique for the detection of trace metals.  The technique is very sensitive but requires careful control of a range of parameters including the conditioning of the working electrode, the temperature and the hydrodyanamics.  In theory nanoelectrodes are immune to stirring and thus this parameter ought to be of far less consequence in the analysis protocol.  In this paper we report of preliminary studies of trace metal analysis using a commercial nanoelectrode structure and examine the robustness of the overall analytical technique.
