Analysis of Boron Isotope Ratio

Analysis of Boron Isotope Ratio
Sponsored by PerkinElmerFeb 18 2021
Boron (B) is an element of interest in many scenarios, particularly for its isotope ratio composition in a range of geochemical, nuclear, paleoproxy, medical and archeological applications.
Boron offers two stable isotopes,
10B and
11B, the latter of which being four times more common. An earlier IUPAC report provided a fixed value (80.1%
11B) for the representative isotopic composition of boron,
1 however, the current edition of the report quotes a natural abundance range of 79.6 – 81.1%
11B.

For purely practical purposes, the earlier presented value is reserved for situations where isotope composition is unknown.
Boron isotope ratios found in nature can vary by around 100‰ (parts per thousand, or permil) or 10% ....
