Abstract

High resolution x-ray emission spectroscopy (HRXES) has been used to record the Si Kβ spectra of a variety of minerals. Distinct changes in peak profile can be related to mineral typo. Representatives spectra were chosen and incorporated, into a computer programme to allow the determination of free silica in binary and quaternary mixtures. The potential of HRXES for the analysis of airborne dust samples is discussed.
