A 41Ca interlaboratory comparison between Lawrence Livermore National Laboratory (LLNL) and the Purdue Rare Isotope Laboratory (PRIME Lab) has been completed. Analysis of the ratios assayed by accelerator mass spectrometry (AMS) shows that there is no statistically significant difference in the ratios. Further, Bayesian analysis shows that the uncertainties reported by both facilities are correct with the possibility of a slight under-estimation by one laboratory. Finally, the chemistry procedures used by the two facilities to produce CaF2 for the cesium sputter ion source are robust and don't yield any significant differences in the final result.

通过加速器质谱法对尿液中的 41Ca 进行超痕量分析：实验室间比较。

劳伦斯利弗莫尔国家实验室 (LLNL) 和普渡稀有同位素实验室 (PRIME Lab) 之间的 41Ca 实验室间比较已经完成。通过加速器质谱 (AMS) 测定的比率分析表明，这些比率在统计上没有显着差异。此外，贝叶斯分析表明，两个设施报告的不确定性是正确的，但一个实验室可能略有低估。最后，这两个设施用于生产用于铯溅射离子源的 CaF2 的化学程序是可靠的，并且不会在最终结果中产生任何显着差异。
