The four main categories are potentiometry (the difference in electrode potentials is measured), amperometry (electric current is the analytical signal), coulometry (charge passed during a certain time is recorded), and voltammetry (the cell's current is measured while actively altering the cell's potential). (wikipedia.org)
Amperometry indicates the whole of electrochemical techniques in which a current is measured as a function of an independent variable that is, typically, time or electrode potential. (wikipedia.org)
Carbon paste electrodes3
In this review is given deal with the carbon paste electrodes and its applications in electrochemical analysis. (ijreiblog.com)
In the main the reason why carbon paste electrodes continue to be popular can be seen mainly because carbon pastes are specifically appropriate for preparing an electrode substantial with chosen structure with pre-determined properties, and simply attainable at least prices, this way, electrodes are mostly considered as very selective sensors to be used for organic and inorganic electrochemistry.

Techniques2
Electroanalytical methods are a class of techniques in analytical chemistry which study an analyte by measuring the potential (volts) and/or current (amperes) in an electrochemical cell containing the analyte. (wikipedia.org)
The EmStat4M is a potentiostat/galvanostat module supporting all common electrochemical techniques, including Electrochemical Impedance Spectroscopy (EIS). (palmsens.com)
Potential4
Potentiometry passively measures the potential of a solution between two electrodes, affecting the solution very little in the process. (wikipedia.org)
Potentiometry usually uses indicator electrodes made selectively sensitive to the ion of interest, such as fluoride in fluoride selective electrodes, so that the potential solely depends on the activity of this ion of interest. (wikipedia.org)
A variant of potentiometry is chronopotentiometry which consists in using a constant current and measurement of potential as a function of time. (wikipedia.org)
This method can reveal the reduction potential of an analyte and its electrochemical reactivity. (wikipedia.org)
