[1]本文提供了地质MPI-DING玻璃KL 2-G、ML 3B-G、StHs 6/80-G、BM 128-G、BM 132-G、BM 90/21-G、T1-G和ATHO-G的主量和微量元素的新分析数据。不同的分析方法被用来获得大量的主要和微量元素的数据，特别是，EPMA，西姆斯，LA-ICPMS，和同位素稀释的TIMS和ICPMS。全球60多个合格的地球化学实验室为分析做出了贡献，使我们能够为多达74种元素提供新的参考和信息值及其不确定性（95%置信水平）。我们遵守了国际地质分析师协会（IAG）对地质参考材料认证的建议。参考值来自16种独立技术的结果，包括确定性（同位素稀释）和比较性原液（e.例如，在一个实施例中，INAA、ICPMS、SSMS）和微量分析（e.例如，在一个实施例中，LA-ICPMS、西姆斯、EPMA）方法。两种或两种以上独立方法之间的一致性以及确定性方法的使用提供了尽可能充分的可追溯性。我们还提出了新的和最近发表的数据的同位素组成的H，B，Li，O，Ca，Sr，Nd，Hf和Pb。结果主要是通过高精度的体技术，如TIMS和MC-ICPMS。此外，还提供了B、Li和Pb的LA-ICPMS和西姆斯同位素数据。
[1] We present new analytical data of major and trace elements for the geological MPI-DING glasses KL2-G, ML3B-G, StHs6/80-G, GOR128-G, GOR132-G, BM90/21-G, T1-G, and ATHO-G. Different analytical methods were used to obtain a large spectrum of major and trace element data, in particular, EPMA, SIMS, LA-ICPMS, and isotope dilution by TIMS and ICPMS. Altogether, more than 60 qualified geochemical laboratories worldwide contributed to the analyses, allowing us to present new reference and information values and their uncertainties ( at 95% confidence level) for up to 74 elements. We complied with the recommendations for the certification of geological reference materials by the International Association of Geoanalysts (IAG). The reference values were derived from the results of 16 independent techniques, including definitive ( isotope dilution) and comparative bulk ( e. g., INAA, ICPMS, SSMS) and microanalytical ( e. g., LA-ICPMS, SIMS, EPMA) methods. Agreement between two or more independent methods and the use of definitive methods provided traceability to the fullest extent possible. We also present new and recently published data for the isotopic compositions of H, B, Li, O, Ca, Sr, Nd, Hf, and Pb. The results were mainly obtained by high-precision bulk techniques, such as TIMS and MC-ICPMS. In addition, LA-ICPMS and SIMS isotope data of B, Li, and Pb are presented.
