Amperometry is an analytical technique used to measure the current that flows through a working electrode as a result of an applied potential. It is a type of electrochemical analysis that is widely used in various fields, including chemistry, biology, and environmental science. The technique is based on the principle that the current flowing through an electrode is proportional to the concentration of the analyte in the solution.

In amperometric measurements, a constant potential is applied to the working electrode, and the resulting current is measured. The current is directly related to the rate of the electrochemical reaction occurring at the electrode surface. This makes amperometry a highly sensitive and selective method for detecting and quantifying analytes.

One of the key advantages of amperometry is its simplicity and ease of use. The technique requires minimal sample preparation and can be performed in real-time, making it suitable for continuous monitoring applications. Additionally, amperometry can be used to detect a wide range of analytes, including ions, molecules, and even biological species.

However, amperometry also has some limitations. The technique is sensitive to changes in the electrode surface, which can affect the accuracy of the measurements. Additionally, amperometry is not suitable for detecting analytes that do not undergo an electrochemical reaction at the applied potential.

In summary, amperometry is a versatile and widely used analytical technique that offers high sensitivity and selectivity for detecting and quantifying analytes. Its simplicity and ease of use make it an attractive option for a variety of applications, although its limitations must also be considered.
