It is sometimes useful to automate some measurements. With EC-Lab and EC-Lab Express, it is possible to automatically perform successive impedance measurements during a potential sweep with the SPEIS (Staircase Potentio Electrochemical Impedance)technique. This technique allows the user to do in the same experiment successive potential steps with an electrochemical impedance spectroscopy measurement on each. For each experiment, the user defines the conditions. One of the applications of this technique is to study electrochemical reaction kinetics along steady-state curves. Note that the same process can be used in galvanostatic mode with the SGEIS technique. VMP3多通道電化學(xué)工作站-16通道
