WebCoulometry is distinguished from voltammetric and amperometric methods by not relying on mass transport current control to obtain a signal dependency on concentration. Coulometry is an absolute method, which means that calibration is generally not necessary as electrical charge can be measured with high accuracy. WebPotentiometry This is the method in which the potential between two electrodes is measured while the electric current (usually nearly zero) between the electrodes is controlled. In the most common forms of potentiometry, two different types of …

WebElectrochemical stripping analysis is a set of analytical chemistry methods based on voltammetry [1] or potentiometry [2] that are used for quantitative determination of ions in solution.
