摘要：
The study proposes a new method for the high-precision determination of bromine isotope ratio in inorganic samples. In the suggested method, inorganic bromide is wet-oxidized into molecular bromine and transferred into the MC-ICPMS by continuous flow of helium. Analysis of natural inorganic bromide samples from various sources revealed identical delta(81) Br values within the range of the method uncertainty. (C) 2011 Elsevier B.V. All rights reserved.
