The refence material IAEA-603 (calcite, CaCO₃) serves as the primary reference material (the highest calibrator) on the VPDB δ¹³C and δ¹⁸O scale. IAEA-603 is certified for the stable isotopic δ¹³C and δ¹⁸O composition.

The reference material IAEA-603 (calcite, CaCO₃) prepared with the aim to replace the reference material NBS19 (exhausted) is certified for the stable isotopic δ¹³C and δ¹⁸O composition. Description of the material, its intended use, results of the characterisation and the values assignment can be found in the Reference Sheet. The material IAEA-603 is supplied as 0.5 g units in flame sealed glass ampoules.
