Progress in the determination of water in glasses and melt inclusions with Raman spectroscopy: A short review

Abstract

This paper is focused on the progress in the determination of water in glasses and melt inclusions with Raman spectroscopy. Using the present "Comparator Technique" the water content of a sample is determined by simple comparison with a known standard. A calibration curve is not necessary. Furthermore, with this technique the water concentration in silicate melt inclusions can be determined without exposing the inclusion for measurements. This is very important for extremely water-rich melt inclusions, which would loose H2O on exposure.
