The start of the first two lines of Notes is normally visible. To view the entire Notes, click the button to the right of the Notes field. A dialog box… read more →
Choose the radio button to the right of the DC Voltage to make the potential relative to the reference electrode. This is the button next to the vs. Eref label.… read more →
Activate the check box next to Init. Delay. The “X” in the box disappears, indicating that the Initial Delay is now off. Notice that the parameters associated with the Initial… read more →
Change the Initial Freq. parameter to 2000 Hz. Editing a numerical field is very similar to editing a text field, by using the mouse or the keyboard. Most numbers in… read more →
Change the Output File parameter to TEST.DTA. Edit a dialog box text field such as the Output File field using either the mouse or the keyboard. Output file names must… read more →
If you have more than one potentiostat, practice selecting potentiostats. When you are comfortable with PStat selectors choose the first potentiostat again, using the mouse or keyboard. The Test Identifier… read more →
Choose Electrochemical Impedance on the Experiment pull-down menu. On the EIS child menu, select Potentiostatic EIS. This selects the standard EIS experiment. Continue the tutorial.
Close any open windows, so that the only program running is the Framework™ software. Continue the tutorial.
The standard EIS technique is useful but it does have limitations. One of these is that its default parameters (such as AC amplitude and frequency limits) are not usable for… read more →
The Electrochemical Impedance Spectroscopy software includes experimental scripts, dynamic-linked libraries, and analysis macros that run under the Gamry Instruments Framework™. The Framework provides a consistent operator’s interface for the EIS… read more →
