In situ EIS measurements on Colombian bronze statues

An in situ assessment of the conservation state of some bronze statues exposed outdoor has been carried out in Colombia, in the historical site surrounding the Puente de Boyacá. Electrochemical Impedance Spectroscopy (EIS) measurements have been performed by using a portable electrochemical interface and by using measuring probes, specifically designed to be capable of working also on slanted surfaces, to be non invasive, and to be removable without damaging the statues with the final aim of developing a long-lasting maintenance methodology for this important complex of Colombian bronze statues.
