pXRF: a study of inter-instrument performance

Journal of Archaeological Science, 2012
Abstract Integrating portable X-ray fluorescence (pXRF) instrumentation into archaeological investigations has generated as much interest as skepticism because several characteristics of the technique limit analytical accuracy and precision. This paper seeks to explore inter-instrument performance in order to assess the potential pXRF instrumentation

Uncertainty and pXRF Measurements

2022
Uncertainty for laboratory instrumentation adheres to the general guide for uncertainty in measurement (GUM). However, portable X-ray fluorescence technology does not lend itself comfortably to the GUM framework for two reasons: calibration models are often kept proprietary by manufacturers and uncertainty is needed on single observation measurements ...
