Abstract
The use of transient electrochemical techniques such as pulse, alternating current, or square wave voltammetry In liquid chromatography with electrochemical detection Is aided by Incorporation of Inexpensive microprocessor-based instrumentation. Construction of microprocessor-based Instrumentation which has been Interfaced to two commercially available systems and stand alone units Is described. Applications to the determination of steroids, surfactants producing tensammetrlc waves, and Inorganic species demonstrate the Increased scope and nature of determinations possible with the microprocessor-aided Instrumentation. Advances presented Include the simultaneous recording of five or more chromatograms on different time scales with different sensltlvies and the recording of complete current-voltage curves at all points In time as required for electrode processes producing tensammetrlc responses.
