Abstract:The 143Nd/144Nd isotopic composition of foraminifera represents one of the most prominent palaeoceanographic proxies enabling tracing of particular water masses due to the short residence time of Nd in seawater and large‐scale provinciality resulting from its lithogenic origin. Despite its wide use, the applicability of foraminiferal Nd isotopic systematics as a palaeoceanographic tracer is largely hampered by the amount of material needed for precise analyses. Here, we analyzed for the first time foraminifera… Show more
“…Compared to the 10 11 U current ampliers, the signal/noise ratios of a TIMS equipped with the 10 12 U and 10 13 U ampliers have been signicantly improved by a factor of three to ten. [41][42][43][44] Theoretically, the enhanced TIMS conguration can obtain high-precision isotopic compositions even for much smaller sample loadings.…”
High-precision measurements of Sr, Nd, and Sm isotopes in precious and single mineral samples are significant in geochemistry and cosmochemistry. It is also a challenge for analytical techniques. In this...

This review covers advances in the analysis of air, water, plants, soils and geological materials by a range of atomic spectrometric techniques including atomic emission, absorption, fluorescence and mass spectrometry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
