Micro-invasive approach for non-destructive XRF analysis on light matrix : inside the Opus Lemovicense

Speed, manageability and above all non-destructivity are the main features that make portable X-ray fluorescence (PXRF) a versatile analytical technique widely used in archaeometry. The extensively use of PXRF instruments in recent years during in situ investigations makes the scientific community wonder how to use in the best way the data collected, as close attention must be paid when analysing non-standard materials such as ancient handcrafted works.
