Evaluating pXRF instrument performance using reference materials

The portable X-Ray Fluorescence (pXRF) instrument provides fast, real-time, non-destructive, multi-element geochemical data (i.e. elemental concentrations) on rocks and minerals at a relatively low cost and with minimal sample preparation. This study quantifies the precision and accuracy of measurements collected by the WGNHS pXRF on reference materials...
