Precise Re isotope ratio measurements by negative thermal ionization mass spectrometry (NTI-MS) using total evaporation technique

High precision determinations of 87Rb/85Rb in geologic materials by MC-ICP-MS

“…[4]). This technique has, e.g., produced Re isotope measurements that have a reported 2σ precision of ±0.1% [5].…”

Os, Pb, and Nd isotope geochemistry of the Permian Emeishan continental flood basalts: Insights into the source of a large igneous province

“…Oxide corrections were made using 17 O/ 16 O = 0.00037 and 18 O/ 16 O = 0.002047 (Nier, 1950). Rhenium isotopic abundances were determined after total evaporation of the samples on the filaments (Suzuki et al, 2004). This method eliminates the effect of instrumental mass fractionation and yields isotopic ratios more accurate than conventional NTIMS measurement techniques.…”

Re–Os geochronology of the Iimori Besshi-type massive sulfide deposit in the Sanbagawa metamorphic belt, Japan

“…Fresh sulfide fragments were carefully hand-picked to avoid contamination by weathered materials or veins and then rinsed with Milli-Q water in an ultrasonic bath for Suzuki et al (2004). Uncertainty of the 187 Re/ 188 Os ratio was determined on the basis of error propagation of Re and Os content errors.…”

“…Instrumental mass fractionation of Os was corrected against a stable 192 Os/ 188 Os ratio of 3.08271 (Nier, 1937). For precise analysis of Re isotope composition, a total evaporation method (Suzuki et al, 2004) was applied to eliminate the effect of instrumental mass fractionation during the measurement. The total procedural blank was $7 pg for Re and $2 pg for Os with a 187 Os/ 188 Os ratio of $0.20.…”
