Hello all, I wanted to ask a question since I'm just so curious about it. I have been doing EIS measurements on carbon electrodes and my results are pretty weird, I am getting either no circle and just a V shape or a circle that starts at negative real axis values lmao. I can give more details on the comments but I don't want my project potentially being recognised by someone I know. The measurement is in 5mM Ferri ferro in distilled water, frequency range 10^5 to 0.1 Hz and it is done in OCP potential
