IAEA-SO-5 aims at calibrations on the VCDT scale for δ34S.

IAEA-SO-5 is a barium sulfate prepared by R. Krouse (University of Calgary, Canada)  and S. Halas (University of Lublin, Poland) by precipitation from sulfate solutions [1].

The isotopic δ34S value of the reference material IAEA-SO-5 is based on interlaboratory comparisons. The material is often used for δ33S calibrations, but this value is not officially agreed.
