Microanalysis of H2O and CO2 in glasses using Raman spectroscopy

Abstract

We have developed a new analytical method for H₂O and CO₂ in silicate glasses by using micro-Raman spectrometry. We analysed H₂O- and CO₂-bearing basaltic glasses using a Raman spectrometer and an FT-IR, and confirmed linear relationships between peak heights of H₂O and CO₃^2- in IR spectra and those in Raman spectra. Therefore, the Raman spectrometry has a potential for quantitative analysis of both H₂O and CO₂ in glass samples.
