Une plateforme pour l'analyse de matériaux par faisceaux d'ions à ARRONAX : Etude de l'effet d'humidité sur les échantillons
Résumé
Quantification of soil pollution with method based on X-ray detection like X-Ray Fluorescence(XRF) suffers of multiple bias (moisture, surface state) especially when it's used for insitu analysis using portable-XRF. In order to study the effect of moisture on the results of an analysis performed using X-Ray, we have performed studies using high energy PIXE/PIGE at the ARRONAX. Samples were made of sand of different type. High energy PIXE/PIGE allows us to avoid bias from surface state and to focus on moisture effect. It also allows to assess the chemical composition of the sample. Results show a different behavior for each element present in volcanic sand.
