# Amperometric Techniques

## Thomas J. Roussel

### 2008

Amperometry is one of a family of electrochemical methods in which the potential applied to a sensing electrode is controlled instrumentally and the current occurring as a consequence of oxidation/reduction at the electrode surface is recorded as the analytical signal

## Highlights

• Amperometry is one of a family of electrochemical methods in which the potential applied to a sensing electrode is controlled instrumentally and the current occurring as a consequence of oxidation/reduction at the electrode surface is recorded as the analytical signal
• When amperometric detectionis used in conjunction with separation techniques such as capillary electrophoresis or liquid chromatography, the sensing electrode is placed at the end of the separation stream so as to permit detection of sample components as they emerge and pass over the electrode surface
