System of Modular Design for Electroanalysis Extended to Thermoelectrochemical Studies

An instrument for electroanalysis extended to thermoelectrochemical studies is presented here consisting of easily available components. An analog potentiostat is combined with a microcontroller. The latter is controlled by an Excel sheet extended by macros written in VBA (visual basic for applications). The worksheet acts as a virtual instrument with front panel and command buttons. Thus, specialized, expansive measuring software packages are unnecessary. The design of new techniques is facilitated by a of graphical representation of pulse sequences or the exciting waveforms. The instrument has proved to be useful for design and performance of non conventional electrochemical techniques working with additional parameters like irradiation or heat. Examples are given for thermoelectrochemical measuring sequences like TPV (temperature pulse voltammetry).
