“…Ionised elements from Li to U are accelerated into a magnetic sector mass spectrometer, where they are separated and their relative abundances are measured, with a detection limit well below 1 ppb (King et al, 1995). Traceability to SI units within stated uncertainties was established at the NRC by analysis of international reference standards (Gusarova et al, 2011). Sixty elements (results summarised in Table 2, data in Electronic Supplement) were analysed at the ppb level.…”

Mixed 235 U-233 U-205 Pb (-202 Pb) tracers for U-Pb isotope-dilution isotope ratio mass spectrometry have been prepared under the auspices of the EARTHTIME Initiative. The methods and results for the preparation and calibration of the U/Pb ratio and isotopic abundances are given, and the various sources of uncertainty are discussed and quantified. The accuracy of the EARTHTIME U-Pb tracer isotopic composition can be traced back to SI units via a series of assay and isotopic composition reference materials combined with the experiments described herein. The parameters used in calculating U/Pb ratios (and inferentially U-Pb dates) have correlated uncertainties that result in a total uncertainty contribution to 206 Pb/ 238 U dates of ± < 0.03% (95% confidence). For suitable terrestrial materials such as zircon, when other sources of uncertainty have been minimised (e.g., open-system behaviour, 238 U/ 235 U variation, intermediate daughter product disequilibrium, common Pb, etc.) the U-Pb tracer calibration uncertainty is a limiting factor in the accuracy of U-Pb geochronology -but less so than the uncertainty in the 238 U and 235 U decay constants (±0.11 and 0.14% 2r). The calibration approach of the mixed EARTHTIME 235 U-233 U-205 Pb (-202 Pb) tracers, in addition to updated values for reference materials (e.g., mixed gravimetric reference solutions), and parameters (e.g., Pb reference material assay), can be applied to other laboratory-specific U-Pb tracers and will facilitate the generation of accurate and directly inter-comparable U-Pb data.

“…It was concluded that the weak cohesion between copper particles gave rise to a higher ablation rate than ablation from solid copper metal. The opposite conclusion was reached by Gusarova et al 32 who found synthetic Cu and Zn pressed powder pins acceptable for calibrating double focusing GD-MS during the determination of 50 elements. Copper and zinc-based CRMs were used for validation.…”

“…2,3 However, the required sample dissolution and separation steps are very timeconsuming, while dilution and the use of high blank reagents can negatively affect detection limits. In addition, as a solutionsampling technique, complex hydrogen-and oxygen-based polyatomic spectral interference can severely hamper the analysis of some rare-earth elements; i.e., 165 Ho + is interfered with by 164 DyH + , 141 Pr + is interfered with by 140 CeH + , and 169 Tm + is interfered with by 168 ErH + and 153 Eu 16 O + . Therefore, a rapid, sensitive, and reliable analytical method for the analysis of trace rare-earth oxides (elements) in high-purity rare-earth oxides is of urgent need.…”

“…However, the use of StdRSFs still leads to relatively large uncertainties (of a factor of approximately two) 14,15 in most cases, and matrix-matched RSFs are always needed to provide more accurate results. Synthetic pressed tablets 5,16 and melting bulks 15 are two commonly used types of metal calibration sample; however, calibration samples of melting bulks and pressed tablets of europium oxides are difficult to prepare because auxiliary conductors are required.…”

Establishing the purities of rare-earth oxides is an important objective as they are extensively used in a variety of applications. Herein, we reported the development of mixing and secondarycathode methods for the microsecond-pulsed and continuous direct-current glowdischarge mass spectrometric analyses of trace rare-earth-oxide contaminants present in europium oxide samples. Matrix effects were corrected for, results were calibrated using relative sensitivity factors derived from pure copper, and the accuracy of the method was validated using Eu2O3 certified reference materials, with relative deviations of less than 15% obtained for most analytes in both modes.
