WebThere are two forms of coulometry: controlled potential coulometry and controlled-current coulometry. A three-electrode potentiostat is used to set the potential in controlled … 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. These methods can be broken down into several categories depending on which aspects of the cell are controlled and which are measured. The four main categories are potentiometry (the difference in electrode potentials is measured), amperometry (electric current is the analytical sig…
