Portable non invasive analyses for Cultural Heritage

Abstract

The requirements that the scientific analyses for Cultural Heritage must have are: nondestructive and noninvasive, multielemental, sensitive, reliable and sufficiently rapid, able to carry out measurements in situ on objects of all types, and to deduce information practically on-line. Among the techniques that fulfill these requirements we find: multispectral imaging, portable EDXRF, Raman and UV-VIS-NIR spectrometry. In this paper we are going to show some cases in which it will appear clear the necessity of the correct order with which applying the non invasive techniques and what data of each of them it is necessary to understand in situ to obtain the maximum of the subsequent scientific techniques.
