myStandards GmbH @ Goldschmidt 2021
Monday, June 28, 2021

This year, one of the most important international conferences in the field of geochemistry, the Goldschmidt, will not take place in France in the beautiful city of Lyon as planned, but again virtually. We have been invited to present the results of our joint collaboration with NIOZ on elemental boron and its isotopes in marine carbonates.

Of course, we would have liked to meet physically and in person with scientists and other companies, but in the current situation the only sensible thing to do is to hold such a large conference with participants from all over the world digitally. All the more we are happy to be part of a workshop where we can present our results of the joint collaboration with NIOZ on elemental boron and its isotopes in marine carbonates. We are extremely grateful and humbled for this opportunity.

Towards improved in situ microanalysis of boron & boron isotopes in carbonates using nano-pellets as reference materials

Previous reference materials for in-situ microanalyses cause an offset in analytical data due to matrix effects. As a result, analytical devices are incorrectly calibrated, which in turn leads to incorrect measurement results. Our nano-pellets are binder-free, ultra-homogeneous and matrix-adapted and thus solve this problem. In collaboration with the NIOZ (Royal Netherlands Institute for Sea Research), we are developing two nano-pellets as reference materials for the determination of boron and boron isotopes in carbonates. The first candidate is the NIOZ Foraminifera House Standard N° 2 Nano-Pellet (NFHS-2-NP). The first measurements with LA-ICP-MS show excellent homogeneity, both within a pellet and between several pellets. The first measurements on boron isotopes are also very promising and will be supported by further analyses. A publication on the entire characterisation is in progress. The second candidate is the NIOZ Boron Isotopic Standard Nano-Pellet (NIBIS-2-NP). The first analyses are promising, too, but considerably more measurement data are required to adequately evaluate this standard.
