This article presents new boron concentrations for nine geochemical reference materials ( GS ‐N, FK ‐N, GL ‐O, BX ‐N, DT ‐N, AN ‐G, GH , Mica‐Fe, Mica‐Mg). After extraction by a modified pyrohydrolysis technique, boron concentrations were measured by ICP ‐ MS . The blank levels for the whole procedure were 0.091 ± 0.020 ng ml −1 or 14 ± 5 ng of boron in total. The method was first validated by measuring nine reference materials with known boron concentrations. The determined boron concentrations are all within the range of recommended or published values, which means that the yields were 100%, and show precisions below 10% for samples containing over 2 μg g −1 of boron.
