Amperometry can be limited by its sensitivity to interference from other electroactive species in the sample, which can lead to inaccurate results. It also requires careful control of experimental conditions, such as pH and temperature, to maintain reliable measurements. Additionally, the technique often necessitates the use of specialized electrodes, which can be costly and may require frequent maintenance or replacement. Lastly, amperometric methods may have a limited dynamic range, making them less suitable for a wide variety of concentrations.
An amperometry measures a current at a fixed applied potential, that is at one point on the current-voltage curve. But in voltammetry it records a number of points on, or a chosen region of the current voltage profile. Thus an amperometry is a fixed-potential voltammetry. submitted by; Jas Raj Subba PSU
Polarography is a type of voltammetry that measures current at varying potentials to analyze electroactive species, while amperometry measures current at a constant potential to study concentration changes over time. In polarography, the potential is scanned to generate a voltammogram, while amperometry uses a fixed potential to monitor changes in current.

Amperometry refers to study of current.it refers to measurement of current, produced by titration reaction, for determining equivalence point (the point at which chemically equivalent quantities of acid and base had been mixed)
