In the last decades the role of non-invasive non-destructive X-ray--based analysis techniques has become more and more important in the field of heritage science due to the successful results obtained for diagnostic and preservation of works of art. INFN-CHNet, the network of the Italian National Institute for Nuclear Physics (INFN) devoted to Cultural Heritage, has been created for developing instruments and methods in this field. Among the others, a new bench-top multi-technique device, based on the INFN-CHNet MA-XRF scanner, has been developed. The available techniques of this instrument are X-ray fluorescence (XRF), X-ray--induced luminescence (XRL), and radiography (RX). XRF is a leader technique for composition analysis. The potentiality of XRL in cultural heritage field was recently tested to study the provenance of lapis-lazuli. The usefulness of RX technique is well established, for instance to study the conditions of panel paintings and wooden statues. Results will be presented.
