Abstract

We present a new analytical method, which allows the simultaneous analysis of fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) ingeological samples. To account for interferences of Fe on the spectral lines of F, of Al on Br-lines, and of Ca on I-lines, we prepared four newhalogen-free calibration glasses. The new method is used to analyze various glass reference materials and crystal-hosted melt inclusions fromthe Azores. Our results show that our new method allows reliable and reproducible analyses of all four halogens in silicate glasses.
