本文包含美国地质调查局GSD-1G和MPI-Ding参考玻璃的广泛的同位素研究结果。13个不同的实验室使用了高精度批量分析(TIMS，MC-ICPMS)和微量分析(LA-MC-ICPMS，LA-ICPMS)技术。为了证明参比玻璃的大尺度和小尺度的均匀性，进行了详细的研究。连同以前公布的来自其他十个实验室的同位素数据，使用国际地质分析师协会关于标准物质认证的建议，确定了H、O、Li、B、Si、Ca、SR、ND、Hf、Pb、Th和U同位素的初步参考值和信息值及其在95%置信度下的不确定度。结果表明，GSD-1G和MPI-Ding玻璃是适合微量分析和大块分析的标准物质。
This paper contains the results of an extensive isotopic study of United States Geological Survey GSD-1G and MPI-DING reference glasses. Thirteen different laboratories were involved using high-precision bulk (TIMS, MC-ICP-MS) and microanalytical (LA-MC-ICP-MS, LA-ICP-MS) techniques. Detailed studies were performed to demonstrate the large-scale and small-scale homogeneity of the reference glasses. Together with previously published isotopic data from ten other laboratories, preliminary reference and information values as well as their uncertainties at the 95% confidence level were determined for H, O, Li, B, Si, Ca, Sr, Nd, Hf, Pb, Th and U isotopes using the recommendations of the International Association of Geoanalysts for certification of reference materials. Our results indicate that GSD-1G and the MPI-DING glasses are suitable reference materials for microanalytical and bulk analytical purposes.
