Potentiometry coulometry and voltammetry
WebIn this chapter we introduced three electrochemical methods of analysis: potentiometry, coulometry, and voltammetry. In potentiometry we measure the potential of an indicator electrode without allowing any significant current to pass through the electrochemical cell. WebElectrochemical methods such as potentiometry, coulometry, amperometry, fundamental principles of Cyclic Voltammetry as well as Electrochemical Impedance Spectrometry were studied and applied. • Various types of advanced sensor materials such as specific ion receptor molecules, membranes and conducting polymers are learnt and applied.
