Evaluation of the Homogeneity of the Uranium Isotope Composition of NIST SRM 610/611 by MC-ICP-MS, MC-TIMS, and SIMS

Abstract: Abstract:As analytical and microanalytical applications employing uranium isotope ratios increase, so does the need for reliable reference materials, particularly in the fields of geochemistry, geochronology, and nuclear forensics. We present working values for uranium isotopic data of NIST 610/611 glass, collected by multicollector inductively-coupled plasma mass spectrometry (MC-ICP-MS), multicollector thermal ionization mass spectrometry (MC-TIMS), and secondary ion mass spectrometry (SIMS). The presence of… Show more

“…For the NIST-610 glass, which was only analyzed using the 200 pA beam current, the average 235 U/ 238 U and 235 U 16 O/ 238 U 16 O ratios and associated 1σ uncertainties were 0.00283 ± 0.00028 and 0.00340 ± 0.00020. Considering uranium occurs at the parts per million level in the NIST-610 glass and that only a 200 pA primary beam current was used, both values compare well with the published 235 U/ 238 U ratio of 0.00239 [21] (note the uncertainty of the published ratio is in the seventh decimal place). For the NIST-610 glass, the average 1σ uncertainty of the individual 235 U/ 238 U ratios is slightly higher at 0.00084 compared to the 235 U 16 O/ 238 U 16 O ratios at 0.00067.…”

“…While solution data was not obtained for the NIST-610 glass and Plesovice zircon reference materials analyzed in this study, there is an LG-SIMS 235 U/ 238 U ratio available for the NIST-610 glass published in [21], whereas the Plesovice zircon (described in [22]) can be assumed to have a natural 235 U/ 238 U ratio. For the NIST-610 glass, which was only analyzed using the 200 pA beam current, the average 235 U/ 238 U and 235 U 16 O/ 238 U 16 O ratios and associated 1σ uncertainties were 0.00283 ± 0.00028 and 0.00340 ± 0.00020.…”
