    Abstract

    Electrolyte resistance is receiving increasing attention as a source of error in electrochemical measurements when not properly managed. This paper is designed as an introduction to, and summary of, this topic. A discussion of electrolyte resistance and its effect on the results of electrochemical measurements is presented. A broad spectrum of methods for minimizing or correcting the errors caused by electrolyte resistance is described. Several advanced ideas are also introduced. References are given to lead the reader to additional information.
