“…Certied U particles were used 26 in a comparison of AMS, SIMS and TIMS for the determination of isotope ratios in individual U particles, an application important for nuclear provenance and safeguarding purposes. The relative errors in the determination of 234 U/ 235 U and 234 U/ 236 U in NBL CRM U200 (uranium isotopic standard) by AMS were <10 and <20%, respectively, whereas the results obtained by ssion track-TIMS and SIMS were within ±5% and ±10% of the certied values, respectively, for both techniques. The relative error and external precision of 234 U/ 238 U and 235 U/ 238 U in the analysis of NBL CRM U850 (uranium (U 3 O 8 ) isotopic standard, 85% U-235) by AMS, SEM-TIMS or SIMS were <10% and <5%, respectively.…”

“…A review (130 references) of approaches for the measurement, assessment and reporting of zircon O isotope data by SIMS provided 233 an analytical framework for geologically meaningful interpretation of such data. Zhang et al 234 investigated the instrumental bias during O isotope analysis of olivines by SIMS using 16 olivine, 9 orthopyroxene and 3 clinopyroxene RMs. A new suite of olivine and pyroxene RMs with an expanded range of compositions was developed to provide better analytical precision and instrumental bias correction in the analysis of olivine and low-Ca pyroxene in primitive chondrule minerals.…”

“…The described method is advantageous over in situ technique with sample masses in the low ng range in terms of precision in Δ′ 17 O. The uncertainty in Δ′ 17 O of 0.04‰ of the continuous flow method falls between that of conventional laser fluorination with 0.008‰ (Miller et al., 2020; Pack et al., 2016; Pack & Herwartz, 2014) and 0.15‰ for SIMS (Zhang et al., 2022).…”

“…However, in situ techniques are limited in terms of analytical precision, in particular with respect to Δ′ 17 O (Bouden et al., 2021; Lampe et al., 2022). Modern SIMS setups provide δ 17 O, δ 18 O, and Δ′ 17 O with 2 σ analytical uncertainties of 0.3‰, 0.2‰, and 0.3‰, respectively (Zhang et al., 2022). Laser fluorination oxygen extraction coupled gas source isotope ratio mass spectrometry (IRMS) is advantageous with regard to precision, again, in particular with respect to Δ′ 17 O. IRMS allows for the identification of triple oxygen isotope Δ′ 17 O variations in the lower parts per million range.…”

In this study, we present a method for high precision Δ′17O (Δ′17ORL = ln(δ17O + 1) – λRL ln(δ18O + 1)) analysis of small mass silicate and oxide materials. The analyses were conducted by laser fluorination in combination with gas chromatography and continuous flow isotope ratio monitoring gas spectrometry. We could analyze the oxygen isotope composition of samples down to 1 μg, which corresponded to about 13 nmol O2. The analytical error (we report the 1σ external reproducibility of a single analysis) in δ18O increases with decreasing sample sizes from ~0.2‰ for ~20 μg samples to ~0.9‰ for 1 μg samples. For Δ′17O, we achieved an external reproducibility of 0.04‰ for a sample mass range between 1 and 27 μg. The uncertainty in Δ′17O is smaller than the uncertainty in δ18O due to the correlated errors in δ17O and δ18O. We applied the method to urban micrometeorites, that is, small meteorites (<2 mm) that were sampled from a rooftop in Berlin, Germany. A total of 10 melted micrometeorites (S‐type cosmic spherules, masses between 11 and 22 μg) were analyzed. The oxygen isotope compositions are comparable to that of modern Antarctic collections, indicating that the urban micrometeorites sample the same population. No indication for terrestrial weathering had been identified in the studied set of urban micrometeorites making them suitable materials for the study of micrometeorite origins.

Cassiterite is the principal ore mineral for tin, and its oxygen isotope is a promising proxy to trace the origin and evolution of ore‐forming fluids, which requires precise and accurate oxygen isotopic analysis. Secondary ion mass spectrometry (SIMS) is a powerful tool for oxygen isotope analysis, especially when samples bear complicated textures, but matrix‐matched reference materials are critical for accurate microanalysis. The only available matrix‐matched reference material for cassiterite oxygen isotope analysis is Yongde‐Cst, and more reference materials are required. Here, we report Piaotang‐Cst as a potential working reference material for cassiterite oxygen isotope microanalysis. Our extensive SIMS microanalysis confirmed that Piaotang‐Cst is relatively homogeneous, with an average two standard deviations (2SD) of 0.49‰ (n = 626). The δ18OVSMOW value of Piaotang‐Cst is 5.33 ± 0.07‰ (2SD, n = 5) as determined by a conventional fluorination isotope ratio mass spectrometer. We also demonstrated that there is no measurable matrix effect caused by the variable contents of trace elements for cassiterite oxygen isotope microanalysis. We proposed that the Piaotang‐Cst can be used as a working reference material for monitoring the external reproducibility and accuracy of SIMS analysis.
