Abstract There is no good practice to present compliance voltage data generated during a 3-electrode potentiostatic measurement. As result engineers are sometimes unaware about the electrical requirements their sensor or cell actually inhibits. This paper proposes method display all information in compact manner. Introduction of six region plot with current plotted third dimension achieves holi...

The use of an electrochemically based probe for in situ determination of heavy metals in groundwater is described. The in situ probe, consisting of a microlithographically fabricated iridium ultramicroelectrode array sensor (UMEA), a custom-built miniaturized potentiostat and microcontroller, is connected to a laptop computer for control and data acquisition. The utility of this probe for rapid...

Bare-metal based REDOX and conductivity sensors that are used to detect ionic species in solution by measuring the electrochemical cell current as the voltage is scanned. The simplicity and robustness of these sensors allows their use in the analysis of ionic species found in natural and drinking water. The measurements include 1) conductivity measurements which provide a gross indication of th...
