Abstract

An 11B spike isotopic reference material CBNM-IRM-611 has been prepared in the form of an H(3)BO(3) solution. The boron concentration was determined by isotope dilution mass spectrometry using the standard reference material NBS SRM 952 in the form of H(3)10BO(3) as reference. CBNM-IRM-611 is certified for its isotopic composition and for its 11B concentration. Uncertainties are 2s or the equivalent. The isotopic reference material is available in quartz ampoules containing approximately 5 g of solution. Using this spike isotopic reference material, 10B or total boron concentrations in unknown samples with non-natural isotopic composition can be determined by isotope dilution mass spectrometry via a measurement of the molar isotope dilution ratio R(B) = 10B/11B in the blend.
