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
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.
Journal ArticleDOI
Lead isotope variability in speleothems—A promising new proxy for hydrological change? First results from a stalagmite from western Germany
Qichao Yang,Denis Scholz,Klaus Peter Jochum,Dirk L. Hoffmann,Brigitte Stoll,Ulrike Weis,Beate Schwager,Meinrat O. Andreae +7 more
TL;DR: In this paper, an aragonitic section of ca. 6 cm length of stalagmite HBSH-1 from the Huttenblaserschachthohle, western Germany was studied.
Journal ArticleDOI
Ostracod shell chemistry as proxy for paleoenvironmental change
Nicole Börner,Bart De Baere,Qichao Yang,Klaus Peter Jochum,Peter Frenzel,Meinrat O. Andreae,Antje Schwalb +6 more
TL;DR: A review of the state of the art of geochemical analyses in microfossils such as ostracods, foraminifera, and corals, and insights in new trace element proxies with the goal to promote the use of trace elements in ostracod shells as paleoenvironmental proxies is provided in this article.
Journal ArticleDOI
BAM-S005 Type A and B: New Silicate Reference Glasses for Microanalysis
Qichao Yang,Klaus Peter Jochum,Brigitte Stoll,Ulrike Weis,D. V. Kuzmin,Michael Wiedenbeck,Heike Traub,Meinrat O. Andreae +7 more
TL;DR: In this article, the homogeneity of trace elements in reference glasses was investigated using the microanalytical techniques EPMA, LA-ICP-MS and SIMS, and the results indicated that all major and most trace elements are homogeneously distributed at micrometre sampling scale in both types of glass.
