Thank you very much for the video Sir. I am beginner in using the EIS and laso Potentodynamic. Would you please to make an video how to use it that two and how to set up the instrument to get data... Thank very much and much aporeciated!
@@mohdhazwan6523 oh many thanks brother. I will check it and if possible I will ask you some parameters value relating to thr EIS and PDP. Saya merasa ga elok pake bhs inggris sesama anak Nusantara/Melayu. Salam kenal dari saya Indonesia... 🙏😍
Hello Dr, I just conducted a Potentiodynamic Polarisation on Nickel Aluminium Bronze and the plots and Ecorr I obtained are all similar to the data I found online by other researches except for the Icorr. The value I obtained is 10 times smaller than the recorded Icorr from online sources. May I know what variables affect the Icorr value? Thank you in advance for your help
There are many factors that can cause lower current value. Is the exposed area is the same with previous work? How about the duration for open circuit potential? What is the concentration of the tested electrolyte? How about the scanning rate..etc..perhaps you can try and narrow the variables
@@mohdhazwan6523 Thank you so much Dr. Could I contact you personally in the future if I have further questions regarding my experiments/project on Nickel Aluminium Bronze. It would be of great help, your videos help me out a lot.
Buenas, le deseo muchos exitos, acabo de ver su video y explica todo bien y profesional, aun que me cuesta por el idioma, tengo el equpo gamry y el software y tengo medidas de (Eis) pero no se modelar en el software el comportamiento que tengo de mis graficas, tengo los archivos con los datos, pero me cuesta la parte de la modelacion para la impedancia electroquimica, cualquier sujerencia o ayuda 🙏, se lo agradecería,
Hola, gracias por seguir el vídeo. ¿Puedo saber qué tipo de muestra está analizando? Tal vez pueda ver sus diagramas primero (pueden enviármelos por correo electrónico) y a partir de ahí podría tener alguna idea sobre el diseño del circuito equivalente.
@@mohdhazwan6523 gracias por responderme, me puede hacer le favor de regalarme su correo para detallarle el proyecto de investigación, de verdad estoy muy agradecido por responder.
@@Hadil-cs1gm it depends on what kinds of discussion you are aiming for..let say for corrosion performance then you will use Rct or Rp but to explain about the best fitting then you will use goodness of fit
Hello I have a problem in polarization impedance EIS, I got a disorderly points that do not form a loop , Is the problem at the level of the reference electrode?
There are lots of possibilities for scattered points. Probably you could check: 1. The connection between your cable and the cell 2. The integrity of your references electrode (perform OCP to check the potential values) 3. Bubbles formed on the surface of the working electrode 4. Frequency range is too low or too high
Hi, you can download the software from Gamry website as long as you have your serial number. If you dont have any Gamry potentiostat, you can download a free ZSimDemo software
Jarang saya nak nampak tutorial dari orang kita. Salute! Thanks for sharing sir.
Terima kasih

Hi, thank you. You can check my previous posted videos regarding on running OCP, EIS and PDP

In Randles which value should i take the Rp or goodness of fit

@@mohdhazwan6523 thank you so much for your help, I had aleeady checked point 1 and 3 there isn't any problem so i will see the others.
@@sayedrim2392 may i know what kind of electrodes that you used and the electrolyte?
@@mohdhazwan6523 it's origalus electrode ( calomel)
Buen video!!
Gracias
Sir, can you please tell me how to find out this e corr i corr without this software? If we use origin then how we can choose the point?
Please watch my recorded lecture on polarization (KAA504). Detailed explanation is on the video
hi, can you send me Gamry EChem Analyst software, please??? thank you in advance.

Thank you for the information and explanation.
Can you write your email or any means of communication? I need to communicate and talk to you
