Generalisation de I'analyse multielementaire par fluorescence X des filtres en fibre par la methode de transmission (AFNOR X 43027)

摘要

the procedures to collect and analyse by AAS the paniculate Lead in atmosphere are described in normative text AFNOR X43021 and X43026. To solve the problems of analytical cost and the definite loss of sample, AFNOR create recently the normalised X-ray Fluorescence analytical procedure X 43027. As now, many elements are of interest, this study illustrates the generalisation of the correction method which is needed to solve a few matrix problems : screen effect between coarse and fine particles which penetrate differently in the structure of the cellulose filters and absorption effect in relation with the total collected particulate matter. We use for that the transmission method and check this ability to measure these perturbing effects.
