Calibrated measurements of the isotopic composition and atomic weight of the natural Li isotopic reference material IRMM-016
The isotope abundance ratio of lithium in the Li isotopic reference material IRMM-016 was redetermined by thermal ionization mass spectrometry by means of synthetic isotope mixtures. This resulted in an absolute ratio n((6)Li)/n((7) Li) of 0.08212 +/-0.00028, and corresponding isotope abundances of 7.589 +/- 0.024 amount % (6) Li, 92.411 +/- 0.024 amount % (7) Li and an atomic weight of lithium of 6.94005 +/- 0.00024. Uncertainties are expanded uncertainties using a coverage factor of two.
