Major, minor and trace element mass fractions determined using ED-XRF, WD-XRF and INAA for three synthetic mullite reference materials (NCS HC 14807; NCS HC 14808; and NCS HC 14809) and five stream sediment reference materials (GBW 07302; GBW 07310; GBW 07311; GBW 07312; and GBW 07405)

This paper is the third in a series of characterization studies conducted by the Center for Applied Isotope Studies, University of Georgia, and the Research Reactor Center, University of Missouri–Columbia, on clay and sediment reference materials. Major, minor and trace element mass fractions were determined using wavelength dispersive and energy dispersive X-ray fluorescence and instrumental neutron activation analysis for three synthetic mullite certified reference materials (NCS HC 14807–14809) distributed by the China National Analysis Center for Iron And Steel and five geological stream sediment certified reference materials (GBW 07302, 07310–07312, 07405) distributed by the National Research Center for Certified Reference Materials in China. We report mass fractions for 10 major elements as oxides and the following minor and trace elements: As, Ba, Ce, Co, Cr, Cs, Cu, Eu, Hf, La, Lu, Nb, Nd, Ni, Pb, Rb, Sb, Sc, Sm, Sn, Sr, Ta, Tb, Th, U, V, Y, Yb, Zn, and Zr.
