Dear Mohsen
It's probably instrumental artifact due either to cabling in your cell or to the cell design itself.

You can see inductance in some systems due to adsorption/desorption but usually at low frequency.
Thank you for your invaluable answers.
Our instrument is an EG&G model 273A that is coupled with a SI1255 FRA.
Please find the aatched file to see the experiment set-up.
Usually, I see this bahaviour in case of bare metals (Ti in contact with brine or Al in contact with chloride solution). In this experiment (see attached figures), bare Al is in contact with 3.5 wt.% chloride solution at room temperature. However, I didn't see this behaviour when coated Al alloy (PEO oxide layer with about 50 micometer) has been exposed to this solution.
Another problem that I see, is a "Reference electrode error message" during some EIS experiments and thus stoping the EIS test.
It is interesting that this error "Reference electrode error message" does not observed or happened when I use other potentiostats (like Autolab or ACM field machine).
Do you think there is a significant relationship between these problems? How do I fix this problem I have?
Scan from 2 MHz to say 100 hz. then u will see that there is no inductance at all. The inductive part that u see is a section of the RC loop related to an adsorbed layer of maybe OH- ion .
