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.

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.

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.

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.

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.
