产品详细介绍
IAEA-CH-7 Synthetic organic polymer 2H and 13C
IAEA-CH-7 (formerly PEF-1) was prepared by H. Gerstenberger and M. Herrmann, Zentralinstitut für Isotopen- und Strahlenforschung, Leipzig, Germany [1,2]. It was checked for isotopic homogeneity and its recommended δ13C value was determined in an international calibration [3].
