Electrochemical impedance spectroscopy
On-site analysis of patinas and coatings present on the surface of metallic Cultural Heritage objects using portable Electrochemical Impedance Spectroscopy (EIS) techniques. To this end, portable electrochemical cells specifically tailored to the needs of cultural heritage and widely verified reliability are used. This allows taking measurements without the need to move the object to be studied in order to determine the protective properties of the existing corrosion products and coatings, the efficiency of different conservation treatments, and its evolution over time.
In-situ analysis of metallic cultural heritage objects objects using portable Electrochemical Impedance Spectroscopy (EIS) techniques. Portable gel polymer electrolyte (G-PE) electrochemical cells have been developed by the service provider, tailored to the needs of cultural heritage and widely verified reliability . This allows taking measurements without the need to move the object to be studied in order to determine the protective properties of the existing corrosion products and coatings, the efficiency of different conservation treatments, and its evolution over time. The electrochemical cell used for in-situ analysis is a gel polymer electrolyte (G-PE) based on a liquid aqueous electrolyte gelled with agar or agarose.
