Isotopic compositions of the elements 2009 (IUPAC Technical Report)
The Commission on Isotopic Abundances and Atomic Weights (CIAAW) of the
International Union of Pure and Applied Chemistry (IUPAC) completed its last update of the
isotopic compositions of the elements as determined by isotope-ratio mass spectrometry in
2009. That update involved a critical evaluation of the published literature and forms the
basis of the table of the isotopic compositions of the elements (TICE) presented here. For
each element, TICE includes evaluated data from the “best measurement” of the isotope
abundances in a single sample, along with a set of representative isotope abundances and
uncertainties that accommodate known variations in normal terrestrial materials. The representative
isotope abundances and uncertainties generally are consistent with the standard
atomic weight of the element Ar(E) and its uncertainty U[Ar(E)] recommended by CIAAW
in 2007.
