Bellatreccia F., Ottolini L., Della Ventura G. Microanalysis of Hydrogen, Boron and Fluorine in Vesuvianite by SIMS, EPMA and FTIR. In: Microchimica Acta, vol. 155 (1-2) pp. 91 - 94. Springer Verlag, 2006.
Vesuvianite, a complex sorosilicate, often contains variable (from trace-to-minor-element) amounts of H, B and F. We describe a microanalytical study of H, B and F in vesuvianite by means of Electron Probe Microanalysis (EPMA), Secondary Ion Mass Spectrometry (SIMS), and single-crystal Fourier-Transform InfraRed (FTIR) spectroscopy. Most crystals investigated are B- (up to 3.67 wt% B2O3) and F-rich (up to 2.38 wt%); H2O ranges from 0.243 to 0.665 wt%. The H data obtained by SIMS allowed us to calibrate the quantitative analysis of H2O by FTIR spectroscopy. The resulting molar absorption coefficient (ɛ i = 100 000 2000 L mol−1 cm−2) is in excellent agreement with working curves available from the literature. Moreover, the SIMS data allowed us to obtain the calibration curve to estimate the B2O3 content on the basis on the FTIR absorbance: a i = 34000 1400 B2O3 (wt%).
