Description

Pulse voltammetry is a characterization tool for electrochemical systems that has been around for many decades. Unlike the more commonly used cyclic voltammetry techniques, the additional degrees of freedom intrinsic to pulse voltammetry permit the decoupling of reaction kinetics from diffusion and allow for the precise measurement of a range of reaction parameters, including the half-wave potential, rate constant, charge transfer coefficient, and diffusion coefficient. These additional degrees of freedom add complexity to the experiments which has proved to be a significant barrier to the widespread adoption of these techniques.Giner aims to develop a software package that will assist with data collection and analysis for a range of electrochemical pulse voltammetry techniques.Ultimately, the tool being developed here will iteratively tune a series of voltammograms to obtain an optimally precise measurement of the system under test along with confidence intervals.The recently completed Phase I program demonstrated successful analysis of Square Wave Voltammetry data on a reversible single electron transfer reaction.Phase II will extend the programs capabilities to analyze more complex reaction systems using a wider array of pulse voltammetry techniques.
