In situ determination of antimony isotope ratios in Sb minerals by femtosecond LA-MC-ICP-MS

Kaufmann, A.B.; Lazarov, M.; Kiefer, S.; Majzlan, J.; Weyer, S. (Cambridge : ChemSoc, 2021)

Here we present a method for in situ determination of stable antimony (Sb) isotope compositions by ultraviolet (UV)-femtosecond-laser-ablation-multi-collector-ICP-MS (fs-LA-MC-ICP-MS). Metallic antimony and a number of Sb ...
A remarkable discovery of electrum on the island of Sylt, northern Germany, and its Scandinavian origin

Schlüter, Jochen; Schuth, Stephan; Fonseca, Raúl O. C.; Wendt, Daniel (Göttingen : Copernicus Publications, 2021)

An electrum-quartz pebble with a weight of 10.4μg was discovered in a cliff of Saalian glaciogenic sediments on the west coast of the German North Sea island of Sylt in 2012. It has a roundish water-worn appearance and ...
Simultaneous determination of δ11B and B/Ca ratio in marine biogenic carbonates at nanogram level

Kaczmarek, Karina; Horn, Ingo; Nehrke, Gernot; Bijma, Jelle (Amsterdam : Elsevier, 2015)

In this study we introduce a new in situ technique which allows the determination of the boron isotopic composition and B/Ca ratios simultaneously at the nanogram level using a combination of optical emission spectroscopy ...
