Certification report for the reference materials ERM-AE123 and ERM-AE124 - Certified for their boron isotope composition

  • Isotope reference materials are essential to enable reliable and comparable isotope data. Besides the correction of mass fractionation or mass discrimination, isotope reference materials are indispensible for validation and quality control of analytical procedures. This report describes the production and certification of two isotope reference materials, ERM-AE123 and ERM-AE124, for boron isotope analysis. The isotopic composition of ERM-AE123 is the unaltered natural-like isotopic composition of the base material. The isotopic composition of ERM-AE124 has been adjusted by mixing two boron stock solutions enriched in 10B and 11B respectively under full gravimetric control. All stock solutions have been prepared fully under gravimetrical control. The corresponding boron isotopic composition has been analysed by TIMS. For both reference materials the isotopic composition obtained on the basis of the gravimetric data agrees very well with the isotopic composition obtained by TIMS.

For both reference materials the isotopic composition obtained on the basis of the gravimetric data agrees very well with the isotopic composition obtained by TIMS. The certified isotope abundances for 10B are 0.19832 (21) for ERM-AE123 and 0.96006 (6) for ERM-AE124. Together with the formerly certified ERM-AE101, -AE102a, -AE103, -AE104a, -AE120, -AE121 and AE122, a unique set of nine certified reference materials (CRM) for boron isotope analysis is now available from BAM covering a range for the 10B isotope amount fraction from 0.2 to 0.96 and for the δ11B value from -20 ‰ to +40 ‰.zeige mehrzeige weniger
