Abstract
The availability of transportable equipment for in situ non-destructive analysis of works of art is considered to be very important. In situ non-destructive study is typically diagnostic, therefore requiring only qualitative or semiquantitative results. In the case of alloys, quantitative results can also be obtained. In Energy Dispersive X-Ray Fluorescence (EDXRF) analysis, portable instruments can now be assembled. For instance, miniaturised X-ray tubes with air cooling and high resolution semiconductor detectors thermoelectrically cooled are now available, allowing the construction of completely transportable apparatus for EDXRF analysis. In this work, aspects regarding methodology of analysis and discussion of the precision obtainable in analysis of ancient metals are presented.
