Boron (B) is studied for its isotope ratio composition in a range of paleoproxy, geochemical, nuclear, medical, and archeological applications. ICP-MS is recognized as a powerful technique for boron isotope analysis. Quadrupole ICP-MS is versatile and not exclusively dedicated to isotope ratio measurements, therefore the appreciation of its isotope ratio capabilities can bring high-quality isotopic ratio analysis into the reach of laboratories with varied analysis needs.

This application note describes the analysis of boron isotope ratios using a NexION^® ICP-MS, demonstrating the instrument’s capabilities to measure at the best possible level of precision.
