Hj. Sanchez et al., XRF ANALYSIS OF VOLCANIC ASH USING SYNCHROTRON-RADIATION, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 84(3), 1994, pp. 408-410
XRF quantitative analyses of volcanic ash were carried out in the Micr
oanalysis Station of the PWA Group of the Frascati National Laboratori
es. Very accurate results were obtained using a conventional XRF arran
gement. These results were compared with the ones obtained by means of
chemical analysis, in a different laboratory, showing a good agreemen
t. Qualitative analyses using a total-reflection setup were performed,
obtaining optimal spectra and detecting new elements not observed in
previous measurements.
