Awsome.... Thanks for your kindly sharing.... I did not expect to find a lesson which containing every piece of EIS analysis. I did not expect such a lesson on RUclips too... Thanks again. Good Luck.
I have done one of my graduation projects on this topic...have my viva exam tomorrow. Thank you for your great help to make my fundamental doubts cleared 💛
When you refer to resistance in 23:33, do you mean electrical resistance or ionic resistance? And how do you distinguish between these two processes in a Nyquist plot?
Thank you for the comment. Practically, consider how the test is applied: Electrochemical Impedance Spectroscopy as a study of an electrochemical cell -- electrodes and electrolyte; whereas, Electrical Impedance Spectroscopy as testing of circuit elements or materials.
Great video. I have a VersaSTAT 3 potentiostat (with EIS available) I am looking for a guide (or manual) to run the Electrochemical Impedance (I am not a specialist)... Does anyone have a recommendation?
Diego, Thank you for wanting to learn more about your VersaSTAT3. There are different resources from AMETEK available including additional videos and technical notes at www.ameteksi.com. There, you can also find contacts for our Applications Team that can help with your specific tests.
@@ametekamt-princetonapplied5482 I have the same situation as Diego, I searched everywhere on intro videos to run the analysis and analyze the data. so far no helpful lead
If the "semi circle" does not start at 0,0 it means that the solution resistance is higher than 0, as expected. The starting point on the X axis (Z_im = 0) is your Z_re, consistent of Solution resistance and connection resistance. When I use 0.1M H2SO4 as electrolyte, the solution resistance in my system is around 30 Ohm. But this value also contains afaik the ohmic resistance of my cables (which are low) and the conductive glass (which is higher than for metals) as well as the solution res. (highest among those)
Thanks for the feedback. This is a content-driven presentation that aims to consolidate topics often covered in full-day or week-long short courses into a single lecture. We do have other videos in our Library that have speakers on camera.
Phan, Thank you for the comment. We will work to improve on future recordings. The Closed Captioning function provides a written text version that has been benefited others with similar preference.

Fantastic video! Some of the most useful instruction on EIS that I have found yet.
Thank you, Bruce! We appreciate the feedback.

Thank you for sharing more helpful information
Kaan, Thank you for this feedback. Please suggest any other related topics that you also think may be valuable.

Thanks for awesome video.....Very informative and helpful to researchers..
Thank you for watching! We are glad you found value in the video.
Great video! We purchased a potentiostat for routine CV and it came with EIS, it is very useful to know we have these extra capabilities!
Thanks for your kindness~!. Helped a lot
Very good video . thank you .
Very informative, thank you!
This is a very helpful video, thanks!
Thank you!
Thank you for this!
You are very welcome! Thank you for watching!
So cool and thank you very much for sharing
oh thanks a lot sir.....for this awesome lecture.....it just cleared my concepts...
Great! Glad we can help!
Thank you very much for your efforts, could you please refer to me how to perform the "Equivalent Circuit Analysis" for the Nyquist plot @22:50
When you refer to resistance in 23:33, do you mean electrical resistance or ionic resistance? And how do you distinguish between these two processes in a Nyquist plot?
Thank you very much for the video!!!, i learned a lot from it!!!!! nice!!!!!!
Thank you for the positive feedback JC. This helps us understand how the community learns more about electrochemical testing and our products.
at 05:50 ... Butler Volmer equation simplifies to I = I0. nFn/RT.... '' with out alpha'' ??? for small overpotencial n...its correct???
A minor typo: Nernstian, not Nernstain. Like Gaussian and Laplacian.
Thank you!
Rafael, thank you for taking the time to watch and comment.
Capacitance is -j/wC, not -1/(jwC).
Thanks :) This helped a lot
You are welcome. Thank you for the comment; feel free to suggest additional topics.
My nyquist ended up not having a semi circle fit, how can i define this? can someone help me?
thank you very much.what is the diference between elctrical impedance spectroscopy and electrochemical impedance spectroscopy?
Thank you for the comment. Practically, consider how the test is applied: Electrochemical Impedance Spectroscopy as a study of an electrochemical cell -- electrodes and electrolyte; whereas, Electrical Impedance Spectroscopy as testing of circuit elements or materials.
thanks !
We appreciate the comment Joaquin. With the growing popularity of the EIS technique, we wanted to provide this content as a resource for researchers.
great job! keep going forward!
The impedance of capacitor should be 1/(jwc) instead of -1/(jwc)...
Thanks, I expressed it differently by multiplying your correct answer by j/j, which yields the same result.
beautiful voice
Thank you for timing the time to comment.

i measure eis for electrode test in a fuel cell.i observed quarter circle not start from 0,0.normal?

Esat Becco, thank you for your kind reply
Nice presentation, but your pace of explanation is too fast to follow.
Thank you for the comment. We will take this into consideration for our next presentation.
Where can I find the first video, "Electrochemical Theory"?
Hi Markus, we're working on it! Just subscribe to our channel and you will be notified once its available. :-)
Great video, great information but presented in a boring way! Hope they improve it.

say too fast. please slow
