Results of analysis of pressed powders. App Note suggests <5% RSD for most analyses. Detectable elements include (but not confined to) Al, Ba, C, Ca, Cr, Fe, H, Mg, Mn, Na, O, Si, Sr and Ti. Detection Limit also provided for Na (10ppm) and Ti (20ppm) but no wavelength or calibration curve supplied. Analysis results for S using PLS shown, but no further explanation.
