NAME XAS SPECTRA OF SYNTHESIZED GLASSES
TYPE Individual Investigation
DESCRIPTION 
In this investigation, multivariate techniques were used to enable accurate X-ray Absorption Spectroscopy (XAS) 
            measurements of Fe, Cr, Mn, and Ti ratios across the whole spectral region through creation of a broad suite of 
            experimentally homogenized glasses of geological relevance for use as XAS standards. Iron, Cr, Mn, and Ti were 
            analyzed as epoxy-mounted polished glass beads using XAS at the GeoSoilEnviroCARS beamline at the Advanced Photon 
            Source, Argonne National Laboratory using a spot size of ca. 1x1 ?m.
