Abstract

We have determined the absolute isotopic composition of ytterbium in six varieties of (terrestrial source) materials based on calibrated mass spectrometry using multi-collector inductively coupled plasma mass spectrometry. Instrumental mass bias was corrected by measuring a series of mixture solutions, which were gravimetrically prepared with three high purity and isotopically enriched isotopes 171Yb, 172Yb and 174Yb. The isotopic compositions of three enriched isotope materials were accurately measured by means of total evaporation thermal ionization mass spectrometry. Six natural-like ytterbium materials including NIM GBW04623 and NIST SRM3166a, yielded the absolute isotopic composition (in at%) of 168Yb 0.12648(22), 170Yb 3.0280(19), 171Yb 14.239(5), 172Yb 21.789(5), 173Yb 16.119(3), 174Yb 31.881(8), and 176Yb 12.817(12). The new atomic weight of ytterbium was calculated to be 173.0417(5) (k = 2) based on these data. In addition, an ytterbium isotopic certified reference material in nitric acid solution (GBW04623) was developed by using a metrological approach, which would be proposed as the delta zero reference for ytterbium.
