IAEA-SO-5 , Barium Sulfate

Materials with known 34S/32S isotopic composition

  • International Chemical Safety Card (ICSC): ICSC_0827

IAEA-SO-5 is a barium sulfate salt prepared by R. Krouse, University of Calgary, Canada, and S. Halas, University of Lublin, Poland, by precipitation from sulfate solutions. The isotopic δ34S value of the reference material IAEA-SO-5 is the result of the statistical evaluation of an interlaboratory comparison.

Analyte Value Unit SD R/I/C
δ34S +0.5 VCDT 0.2 R

(R/I/C) Classification assigned to the property value for analyte (Recommended/Information/Certified)
