IAEA-CO-9Barium Carbonate Inorganic Mineral
The IAEA-CO-9* material is barium carbonate powder. It was prepared by C. A. Brenninkmeijer, Atmospheric Division, National Institute for the Atmosphere and Hemisphere, Lower Hutt, New Zealand, using CO2 from natural gas and precipitation as carbonate by NaOH solution and barium sulfide [1]. Its recommended δ13C value was determined in an international calibration [2]. The recommended δ18O value is a mean from data of an interlaboratory comparison [1].
Analyte Value Unit SD R/I/C δ13C -47.321 ‰VPDB 0.057 C δ18O -15.6 ‰VPDB 0.2 R (R/I/C) Classification assigned to the property value for analyte (Recommended/Information/Certified)
