Sažetak
The use of electrochemical impedance spectroscopy (EIS) in the diagnosis of cultural objects represents a very powerful technique that can help conservators identify which object needs intervention to evaluate the effect of a treatment. EIS is still far from being standard or routinely applied because of difficulties both in applying this technique to cultural objects-which requires in situ measurements-and in interpreting the results. A major challenge in performing EIS measurements in the field is the placement of a cell with liquid electrolyte on an irregular, uneven, and thin surface of the artefact. One approach to this problem is based on the use of a solid electrolyte instead of a liquid electrolyte. In the present study, we investigate the concept of rapid in situ measurements on copper and bronze, as well as on patinated bronze without and with a protective layer, using a conductive paste electrolyte that provides a non-aggressive environment in a two-electrode system consisting of a substrate and a single flexible (counter/reference) electrode. Comparative measurements were performed with both a screen- printed carbon electrode and a conventional electrochemical cell. In this way, electrochemical impedance spectroscopy measurements were performed in two- and three-electrode cell configurations using conductive paste electrolyte to better define the influence of the various parameters of the experimental setup on the recorded data.
