As we have
experienced that commercial 9Be carriers in use for
accelerator mass spectrometry (AMS) contain elevated levels
we have published values of these compared to customised 9Be
carriers from minerals already two times:
S. Merchel, M. Arnold, G. Aumaître, L. Benedetti, D.L.
Bourlès, R. Braucher, V. Alfimov, S.P.H.T. Freeman, P. Steier, A.
Wallner, Towards more precise 10Be and 36Cl data
from measurements at the 10-14 level: Influence of sample
Instr. Meth. Phys. Res. B. 266 (2008) 4921-4926.
S. Merchel, R. Braucher, J. Lachner, G. Rugel, Which is the best
9Be carrier for 10Be/9Be accelerator mass
spectrometry?, MethodsX 8 (2021) 101486.
These results have yet shown that 10Be/9Be can vary from LOT to LOT. Hence, to keep the AMS community up-to-date we are encouraging to communicate 10Be/9Be measured at any AMS facility. So, if you have any new 10Be/9Be data of commercial 9Be carriers, please let me know and I will add it to the table below to overcome the necessity to write a third paper on this topic. ;-)
|Company||LOT number||10Be/9Be||AMS facility||Data provided by|
|LGC||1072683-55||(3.08 ± 0.30) x 10-15||ASTER||Régis Braucher|
|LGC||1143802-8||(3.50 ± 0.31) x 10-15||ASTER||Michal Šujan|
Thanks to the AMS facilities and users providing the new data!
