dc.description.abstractEnThe development of portable X-ray fluorescence (pXRF) equipment for the chemical analysis of ceramics has enabled the acquisition of larger quantities of data, despite the limitations in sensitivity compared to traditional analytical techniques such as WD-XRF, ICP-MS, and NAA.As part of an International Research Network pXRF-CUN programme (pXRF Ceramic Users Network, 2021-2025), led by the CEAlex, various partners are working together to compare and share the data obtained by their pXRF equipment on ceramic materials. To this end, an initial selection of 18 examples of ceramics and international standards has been made to create an intercalibration kit. Initially, ten kits of glass beads were prepared and distributed to partners. In parallel, the measurements obtained by ICP-MS and WD-XRF are almost identical and could be considered as reference. The same kit, in powders forms was also provided to question the preparation of the analysis medium and broaden the methodological questioning.Thus, the results obtained were discussed, in terms of detection sensitivity, resolution, accuracy, precision, but also sample preparation.Accordingly, a new ceramic kit comprising 18 fired bricks has been prepared from clays collected from known provenances, covering the range of the most common ceramic compositions. This stage in the intercomparison of 11 portable pXRF systems provides an opportunity to engage in a constructive debate on the quality of the data obtained and the potential for using it by other teams. However, the challenge of intercalibration of equipment dedicated to the analysis of ceramic material remains more complicated to implement. The results will be presented here and published in detail soon.
