The Scientific Laboratories are equipped with state-of-the-art instrumentation, used for conducting analytical campaigns that support archaeological and art historical scholarship, conservation treatments, and educational activities related to the University of Turin’s Master’s Degree. This equipment is also employed to implement environmental monitoring programs and to develop research projects at the national and international level.
The available techniques include both non-invasive and micro-invasive methods, such as 2D and 3D imaging, optical and electron microscopy, elemental and molecular spectroscopies, biological investigations, and environmental monitoring systems.
Additionally, the Laboratories house a unique radio-tomographic system specifically designed for examining large-scale artifacts. This technology was assembled within the neu-ART research project (2010-2013), funded by the Piedmont Region and developed in collaboration with the University of Turin’s Department of Physics and with the Turin branch of the National Institute for Nuclear Physics (INFN).
