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
No Evidence for Cerium Dioxide Nanoparticle Translocation in Maize Plants
Karin Birbaum,Robert Brogioli,Maya Schellenberg,Enrico Martinoia,Wendelin J. Stark,Detlef Günther,Ludwig K. Limbach +6 more
TL;DR: It is demonstrated that 50 μg of cerium/g of leaves was either adsorbed or incorporated into maize leaves, which may indicate that the biological barriers of plants are more resistant against nanoparticle translocation than mammalian barriers.
Journal ArticleDOI
Abyssal peridotite Hf isotopes identify extreme mantle depletion
Andreas Stracke,Andreas Stracke,Jonathan E. Snow,Eric Hellebrand,A. von der Handt,A. von der Handt,Bernard Bourdon,Bernard Bourdon,Karin Birbaum,Detlef Günther +9 more
TL;DR: In this article, the authors presented new Hf and Nd isotope analyses of clinopyroxene (cpx) from abyssal peridotites from the Gakkel Ridge in the Arctic Ocean, the Southwest Indian ridge and the South Atlantic.
Journal ArticleDOI
Refractory element fractionation in the Allende meteorite: Implications for solar nebula condensation and the chondritic composition of planetary bodies
Andreas Stracke,Andreas Stracke,Herbert Palme,Marko Gellissen,Carsten Münker,Thorsten Kleine,Thorsten Kleine,Karin Birbaum,Detlef Günther,Bernard Bourdon,Bernard Bourdon,Jutta Zipfel +11 more
TL;DR: In this article, the authors investigated the effect of sample heterogeneity on the major and trace element composition of the CV chondrite Allende using a single 30-g slice, which is 22.5 cm2 in dimension and 4mm thick.
Journal ArticleDOI
Fundamental studies on the ablation behaviour of Pb/U in NIST 610 and zircon 91500 using laser ablation inductively coupled plasma mass spectrometry with respect to geochronology
TL;DR: In this paper, the authors investigated the limitations of non-matrix matched quantification of the Pb and U system and showed that at certain operating conditions the loss of pb and the retention of U within the crater are equal.
