Abstract
We have prepared a large volume of pure, concentrated and homogenous zinc standard
solution. This new standard solution is intended to be used as a primary reference standard for
the zinc isotope community, and to serve as a replacement for the near-exhausted current
reference standard, the so-called JMC-Lyon Zn. The isotopic composition of this new zinc
standard (AA-ETH Zn) has been determined through an inter-laboratory calibration exercise,
calibrated against the existing JMC-Lyon standard, as well as the certified Zn reference
standard IRMM-3702. The data show that the new standard is isotopically indistinguishable
from the IRMM-3702 zinc standard, with a weighted d66/64Zn value of 0.28±0.02‰ relative to
JMC-Lyon. We suggest that this new standard be assigned a value d66/64Zn of +0.28‰ for
reporting of future Zn isotope data, with the rationale that all existing published Zn isotope
data are presented relative to the JMC-Lyon standard. Therefore our proposed presentation
allows a direct comparison with all previously published data, and that is directly traceable to
a certified reference standard, IRMM-3702 Zn. This standard will be made freely available to
all interested labs through contact with the corresponding author.
