Rapid accurate isotopic measurements on boron in boric acid and boron carbide

Talanta. 1986 Apr;33(4):291-4. doi: 10.1016/0039-9140(86)80076-5.

Abstract

A procedure is described whereby rapid and accurate isotopic measurements can be performed on boron in boric acid and boron carbide after fusion of these compounds with calcium carbonate. It allows the determination of the isotopic composition of boron in boric acid and boron carbide and the direct assay of boron or the (10)B isotope in boron carbide by isotope-dilution mass spectrometry.
