Calculating and setting the initial values of the parameters are performed through GUI control, that is, by simply dragging a cursor and clicking buttons. The partial impedance elements include a resistor, capacitor, inductor, a resistor parallelly connected to a capacitor, Warburg impedance, Gerischer impedance, and Havriliak-Negami impedance. Figure 2: Course of potential during a cyclic voltammetric measurement (screenshot of analysis program: Gamry Echem AnalystTM). Data files generated by experiments in Gamry Framework then can be analyzed in the Echem Analyst. The initial parameter values of an equivalent circuit model, which is represented by a peculiar script, can easily be obtained by selecting a data point using a cursor on the logarithm of frequency versus imaginary part of impedance plot by GUI operation and setting a partial impedance element on the graphic control panel. Gamrys data0acquisition program called Framework. ![]() This new function can be applied without limitation of the equivalent circuits on the basis of a measurement model. We developed an impedance analysis software implementing new function for finding an appropriate initial parameter set for impedance spectrum analysis using an interactive graphical user interface (GUI). To open a data file (.DTA extension) for analysis: 3 Choose the desired. ![]()
