Values reported were obtained with a Spectro Analytical Instruments EOP ICP; perform anc e m ay vary with instrument and should be independently verified. Values are c ertified b y Inorganic Ven tures INC. at 3x and 10x the appro xim ate ins trum enta l LOD [12]. Bo ld values are qualitative only because of low recove ry. Other digestion techniques m ay be m ore appropriate for these elements and their compounds.
