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[1–3] 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
