Impact-induced sublimation drives volatile depletion in carbonaceous meteorites Open
Carbonaceous chondrites are amongst the most chemically primitive solid materials in the Solar System, yet many are depleted in moderately volatile elements. Here, we report enrichments in heavier zinc isotopes in heated carbonaceous chond…

Overcoming analytical limitations with 5-line multi-dynamic Nd isotope measurements by thermal ionisation mass spectrometry Open
The extinct 146Smsingle bond142Nd radio-isotope chronometer is a valuable tool to study the first 500 Myr of Earth's history, although the entire range of variations of the 142Nd/144Nd ratio in terrestrial materials is on the order of 20 p…

Impact of aging on copper isotopic composition in the murine brain Open
Aging is the main risk factor for Alzheimer's disease (AD). AD is linked to alterations in metal homeostasis and changes in stable metal isotopic composition can occur, possibly allowing the latter to serve as relevant biomarkers for poten…

Copper Isotope Compositions Measured Using a Sapphire Dual Path MC-ICPMS with a Collision/Reaction Cell Open
We present a new approach to Cu isotopic measurements using a state-of-the-art Nu Sapphire multicollector inductively coupled plasma source mass spectrometer equipped with a collision/reaction cell (CRC-MC-ICPMS). We investigate the effect…

Assessment of matrix effects induced by chloride, sulfate and dissolved organic carbon during Si isotope measurements by MC-ICP-MS under wet plasma conditions Open
This study demonstrates that silicon isotope measurement under wet plasma shows larger tolerance to sample-based matrix effects caused by anions and dissolved organic carbon compared to dry plasma.

Fani Maoré, a new “young HIMU” volcano with extreme geochemistry Open
Intraplate volcanism provides remarkable insight into diverse sources in the mantle because its source can be quite shallow, or as deep as the core-mantle boundary, and its origin can be as diverse as recycled crustal material or undiffere…

Collision course; high-precision mass-independent and mass-dependent calcium isotope measurements using the prototype collision cell MC-ICPMS/MS, Proteus Open
This paper reports measurements of mass-independent and mass-dependent Ca isotope variations using the prototype collision cell MC-ICPMS/MS, Proteus. Helium and hydrogen gases are introduced into the collision cell and the well characteris…

Primordial formation of major silicates in a protoplanetary disc with homogeneous <sup>26</sup> Al/ <sup>27</sup> Al Open
Primordial refractory silicates record evidence that aluminum-26 was efficiently mixed across different solar system sources.

Using Mg Isotopes to Estimate Natural Calcite Compositions and Precipitation Rates During the 2010 Eyjafjallajökull Eruption Open
Chemical weathering of silicate rocks is a key control on the long-term climate, via drawdown of atmospheric CO2. Magnesium isotopes are increasingly being used to trace weathering, but are often complicated by several coincident fractiona…
