A portable system has been recently developed; it combines X-ray fluorescence (XRF) and X-ray diffraction (XRD) techniques, allowing simultaneous elemental analysis and mineral phase identification. A low power (30 W) Cu anode air cooled X-ray source is used, equipped with a polycapillary semi-lens to provide a parallel beam. The system has been designed without mechanical movements and its structure allows the analysis of objects with different shapes; the instrumentation is particularly suitable for materials identification in cultural heritage applications where artefacts have often non flat surfaces and irregular shapes. In the present paper we present the design of the instrument and the first measurements performed with it. In particular the results show that it is possible to identify the main crystalline phases present in the samples and to perform this analysis in relatively short times, from 30 minutes to one or two hours.
