5 | Rubidium | Rb | mg/kg | Andrews, John T | Isotope dilution concentration determinations accurate to ~1 % for Rb and Sr, and 0.5 % for Sm and Nd. Total procedural blanks averaged ~1 ng for Sr, and 100 pg for Nd, during study period. | |
6 | Strontium | Sr | mg/kg | Andrews, John T | Isotope dilution concentration determinations accurate to ~1 % for Rb and Sr, and 0.5 % for Sm and Nd. Total procedural blanks averaged ~1 ng for Sr, and 100 pg for Nd, during study period. | |
7 | Rubidium-87/Strontium-86 ratio | 87Rb/86Sr | Andrews, John T | Measured 87Sr/86Sr ratios were analyzed using four-collector static mode measurements. Eight measurements of SRM-987 during study period yielded mean 87Sr/86Sr = 0.71030 +/- 2. | ||
