XRF quantitative analyses of volcanic ash were carried out in the Microanalysis Station of the PWA Group of the Frascati National Laboratories. Very accurate results were obtained using a conventional XRF arrangement. These results were compared with the ones obtained by means of chemical analysis, in a different laboratory, showing a good agreement. Qualitative analyses using a total-reflection setup were performed, obtaining optimal spectra and detecting new elements not observed in previous measurements.
