International audienceX-ray fluorescence is an efficient method for quantitative elemental analysis of atmospheric aerosol assuming thin layer hypothesis. The major difficulty of Ihis kind of sample is due to the possible absorption of the fluorescent radiation by the sample matrix. For this reason , we have experimentally determined the conditions of thin layer analysis for a set of aerosol samples collected in Cape Verde Islands, by applying an emission-transmission method, which consists of a measurement of the sample transmission using the 'radiator' technique to correct the absorption effect in relation to the concentrations for samples of intermediate thickness. From the experimental results, a linear relation has been established bet...
