Voltammetric techniques of analysis: the essentials

Abstract

This text is written for a course on instrumental methods of quantitative analysis. It summarizes the basic concepts of modern voltammetric techniques of analysis. The guiding concept of this text is to demonstrate how the ratio of faradaic to capacitive currents decides about the sensitivity of the techniques, and how this ratio can be increased by electronics, electrode construction and by chemical means. Finally, the advantages and disadvantages of voltammetric techniques of analysis are briefly described.
