How Well Do We Know VPDB—Part 2: Interlaboratory Assessment of Existing <i>δ</i> <sup>13</sup> C <sub>VPDB</sub> Reference Materials
The reported values for IAEA-610, -611, -612, and USGS44 on the δ<sup>13</sup>C<sub>VPDB</sub> scale are -9.114 ± 0.011‰, -30.815 ± 0.011‰, -36.739 ± 0.020‰, and -42.073 ± 0.015‰, respectively. Within their measurement uncertainty they are identical to previously published values. Finally, we provide values on the δ<sup>13</sup>C<sub>VPDB</sub> and δ<sup>13</sup>C<sub>VPDB-LSVEC</sub> scales for some RMs that are routinely used in elemental analysis-isotope ratio mass spectrometry.
