Rapid tracking of metals and other minerals in solid contaminated environments matters (soil, waste) thanks to non-destructive and rapid on-site methods with X-fluorescence

Summary

Following a literature review, this study set out to assess the performance of two types of field device: a portable pistol-type device and a mobile device. The influence of several parameters was tested in order to highlight the advantages and limitations of these devices. Experiments and measurements, covering particle size, water content, number of measurements, surface preparation and tablet preparation, were carried out on different matrices. The results of this study showed that the accuracy of the equipment does not generally meet the regulatory or technical thresholds required by users. It is therefore necessary, for each matrix, to set up appropriate instrument calibration, preparation and measurement protocols in order to obtain representative and interpretable results.
