Not one, but TWO YouTube videos on EIS have been released!
The first, 5 Best Practices for Accurate Electrochemical Impedance Spectroscopy (EIS) Data, shares the best practices for setting up and performing EIS (because experimental setup should be straightforward, and not interfere with the data and results).
The second, Selecting PEIS vs GEIS for Battery Impedance Measurements, discusses the difference between and how to select Galvanostatic EIS versus Potentiostatic EIS.
Electrochemical Impedance Spectroscopy (EIS) is one of those analytical techniques that can be more of an art than a science to achieve results.
It’s amazing (and frustrating) how much electro-magnetic interference (EMI) or alligator clip placement on battery tabs can cause noise and errors in your data.
For these videos, in my former role as Technical Director at Electric Goddess I partnered with Admiral Instruments using their Squidstat Plus electrochemical workstation to perform experimental demonstrations! It was a thrill to be able to share hands-on experimentation in a video!
If you have any questions about EIS and how it can be used to study your electrical or electrochemical system, please let me know. I’m happy to guide you to the best resource for you.
Also, I am always open to YouTube partnerships and collaborations.
