Abstract

A 6Li spike isotopic reference material CBNM-IRM-615 has been prepared in the form of Li(2)CO(3) in HCl. The lithium concentration was determined by isotope dilution mass spectrometry against NBS SRM 924 Li(2)CO(3). CBNM-IRM-615 is certified for its isotopic composition of 95.610 +/- 0.025 amount % 6Li, 4.390 +/- 0.025 amount % 7Li, and for its 6Li concentration of 3.825 +/- 0.027 x 1.0 E-3 mol 6Li/kg of solution. Uncertainties are 2s or the equivalent. The isotopic reference material is available in quartz ampoules containing approximately 5g of solution. Using this spike isotopic reference material, 7Li or total Li concentrations in unknown samples can be determined by isotope dilution mass spectrometry via a measurement of the molar isotope dilution ratio R(B) = 6Li/7Li in the blend.
