	Properties: Isotope amount ratio (11 B) / (10 B) 24.04 dimensionless Isotope amount ratio (10 B) / (11 B) 0.041 60 dimensionless Isotope abundance (10 B) 0.960 06 dimensionless Isotope abundance (11 B) 0.039 94 dimensionless Molar mass 10.052 73 g/mol			Remarks: Boric acid in water with 10B amount fraction of 96.006% PFA - bottle, aqueous solution, 20 mL Intended Use: It is designed to determine mass discrimination in Inductively Coupled Plasma Mass Spectrometry (ICP-MS. ERM-AE124 may also be used for isotope tracer studies and as spike for isotope dilution analysis. In the latter case, however, the characterization of the boron mass fraction by reverse IDMS at the time of use might be advisable, when low measurement uncertainties (<1 % relative) are aimed at.
