Materials with known 34S/32S isotopic composition
Unit Size: 0.5 g
IAEA-S-3 silver sulfide was prepared by B. W. Robinson, Department of Scientific and Industrial Research, Lower Hutt, New Zealand. The starting material for IAEA S 3 was sphalerite provided by S. Halas, University Maria Curie-Sklodowska University, Lublin, Poland with δ34S vs. VCDT near 30 ‰ [1, 2]. The isotopic values of the reference material, IAEA-S-3 are the results of the statistical evaluation of inter-comparison exercises.
