產(chǎn)品詳細介紹
IAEA-CO-1Marble Inorganic Mineral
A Carrara marble supplied to IAEA by IMEG, Viareggio, Italy, was originally intended as 14C quality control material IAEA-C1. The fraction of the material ground to a fine powder with grain size below 100 μm is called IAEA-CO-1 and is intended for stable isotope measurements [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 +2.492 ‰VPDB 0.030 C δ18O -2.4 ‰VPDB 0.1 R (R/I/C) Classification assigned to the property value for analyte (Recommended/Information/Certified)
