Abstract
μXRF is a powerful instrument for non-destructive characterization of materials of cultural interest. At the XLab Frascati Laboratory this technique is already well performed thanks to the polyCO set equipment allowing simultaneous μXRF 2D mapping. However, due to the strict demand for in situ analysis in this particular field, a new portable μXRF spectrometer equipped with a full polycapillary lens conjugated with a transmission anode X-ray tube is proposed.Many cultural objects are characterized by elements (Ag, Sn, etc.) with high energy fluorescence K-lines. Thus, the capability of a full lens to deliver a high energy fraction of X-ray spectrum, in order to excite the fluorescence K-lines of such elements, is tested.
