At the same time, we detected that one of the electrodes was stained(oxidation was performed), so we changed the electrodes metal, avoiding at the same time heating of the electrodes or medium and the noise that this could imply. Instead of gold we used chrome electrodes recovered by platinum.<br><br> | At the same time, we detected that one of the electrodes was stained(oxidation was performed), so we changed the electrodes metal, avoiding at the same time heating of the electrodes or medium and the noise that this could imply.
