                        产品详细介绍 IAEA-CO-8Calcite Mineral 13C and 18O The reference material IAEA-CO-8* is a natural carbonatite originating from Schelingen at the Kaiserstuhl, Germany. The material was ground to a grain size from 0.09 to 0.5 mm and put at the IAEA’s disposal by Geologisches Landesamt, Freiburg, Germany [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]. The material contains other mineral grains and may not be recommended for analysis of small aliquots. Analyte Value Unit SD R/I/C δ13C -5.764 ‰VPDB 0.032 C δ18O -22.7 ‰VPDB 0.2 R
