Electrochemistry provides a powerful set of tools for analysis. Its power derives from the fact that electrochemistry is inherently chemical in nature. This instrumentation article describes developments in current-carrying electrochemical detectors. It is possible to argue that these detectors, out of all other developments in electroanalytical chemistry, have had the greatest impact on real analytical chemistry since the development of ion-selective electrodes. Within the context of electrochemical detectors, the authors will discuss three topics that are important to all analytical chemists: signal and noise generation and signal-to-noise ratio (S/N), the improvement of qualitative information content, and control of selectivity of the detector. In each area there are many opportunities to increase our knowledge; they describe some relevant research. They demonstrate that there is much to learn and that the electrochemical approach can be made more versatile and powerful that it is today.
