Determination of Reference Values for NIST SRM 610–617 Glasses Following ISO Guidelines
Klaus Peter Jochum,Ulrike Weis,Brigitte Stoll,D. V. Kuzmin,Qichao Yang,Ingrid Raczek,Dorrit E. Jacob,Andreas Stracke,Karin Birbaum,Daniel A. Frick,Detlef Günther,Jacinta Enzweiler +11 more
TL;DR: In this article, the authors presented new reference values for the NIST SRM 610-617 glasses following ISO guidelines and the International Association of Geoanalysts' protocol, and determined quantitatively possible element inhomogeneities using different test portion masses of 1, 0.1 and 0.02μg.
Journal ArticleDOI

Klaus Peter Jochum,Ulrike Weis,Beate Schwager,Brigitte Stoll,Stephen A. Wilson,Gerald H. Haug,Meinrat O. Andreae,Jacinta Enzweiler +7 more
TL;DR: In this article, the authors present new reference values for nineteen USGS, GSJ and GIT-IWG rock reference materials that belong to the most accessed samples of the GeoReM database.
Journal ArticleDOI
Accurate trace element analysis of speleothems and biogenic calcium carbonates by LA-ICP-MS
Klaus Peter Jochum,Denis Scholz,Brigitte Stoll,Ulrike Weis,Stephen A. Wilson,Qichao Yang,Antje Schwalb,Nicole Börner,Dorrit E. Jacob,Meinrat O. Andreae +9 more
TL;DR: In this article, a protocol for precise and accurate LA-ICP-MS analysis of calcite and aragonite layers of a stalagmite and found large variations for Mg, Zn, Sr, and U in ostracod shells, indicating the potential for paleoclimate research.

GSD-1G and MPI-DING Reference Glasses for In Situ and Bulk Isotopic Determination
Klaus Peter Jochum,Steven A. Wilson,Wafa Abouchami,Marghaleray Amini,Marghaleray Amini,Jérôme Chmeleff,Jérôme Chmeleff,Anton Eisenhauer,Ernst Hegner,Linda M. Iaccheri,Bruno Kieffer,Joachim Krause,William F. McDonough,Regina Mertz-Kraus,Ingrid Raczek,Roberta L. Rudnick,Denis Scholz,Grit Steinhoefel,Brigitte Stoll,Andreas Stracke,Sonia Tonarini,Dominique Weis,Ulrike Weis,Jon Woodhead +23 more
TL;DR: In this paper, the results of an extensive isotopic study of United States Geological Survey GSD-1G and MPI-DING reference glasses were presented. And the results indicated that GSD1G is suitable reference materials for microanalytical and bulk analytical purposes.
Journal ArticleDOI
