                        产品详细介绍 IAEA-600Caffeine Pure Substance 13C and 15N Reference material IAEA-600 is aimed at δ13C calibrations by TC/EA technique; its δ15N is provided for information purpose. IAEA-600 was prepared by W. Brand and R. Werner, Max-Planck-Institute for Biogeochemistry, Jena, Germany, from commercially produced pure caffeine. Its recommended δ13C value was determined in an international calibration [1]. For this reference material the δ15N value war determined in one laboratory only and therefore is only an information value. Analyte Value Unit SD R/I/C δ13C -27.771 ‰VPDB 0.043 C δ15N +1.0 ‰air N2 0.2 I 
 (R/I/C) Classification assigned to the property value for analyte (Recommended/Information/Certified)
