With the ever-increasing power and low prices of modern laboratory microcomputers it is becoming common for the average researcher to routinely employ sophisticated data analysis methods. Most of these methods have been the subject of study by researchers associated with the discipline of analytical chemistry known as chemometrics. Although the application of chemometrics has become routine in all fields of analytical chemistry, this article is focused on those applications appearing in electroanalytical chemistry. Examples of chemometric solutions to a variety of electrochemical problems are reviewed in conjunction with brief presentations of the relevant chemometric background.
