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.
