Scientific and technological expertise is carried out through a set of non-destructive and non-contact methods of research in the visible, ultraviolet, infrared and X-ray regions of the electromagnetic spectrum, as well as on the basis of the selected micro-samples in the clearly marked and designated locations for infrared spectroscopy with Fourier transform (FTIR), and on the basis of the complex micro-chemical analysis. The clear positioning of sampling locations allows us to compare the results with the studies in the other expertise centres.
