IAEA-30313C Labelled Sodium-Bicarbonate
IAEA-303 was aimed at δ13C calibrations at high δ13C enrichments.
Reference material IAEA-303 consisted of two sodium bicarbonates (A and B), which were prepared from NaH13CO3. The isotopic values were established on the basis of inter-laboratory comparison organized by the IAEA Section of Nutritional and Health Related Environmental Studies [1].
