Reference Sheet: VSMOW2
VSMOW2 (Vienna Standard Mean Ocean Water 2) is an international measurement standard for stable isotope analysis. This water material was prepared at the IAEA Isotope Hydrology Laboratory in 2006 to replace the exhausting VSMOW material. VSMOW2 was mixed from carefully calibrated distilled natural water samples in order to obtain a stable isotopic composition as similar as possible to that of the original VSMOW. Five selected laboratories provided calibration measurements in direct comparison to VSMOW. All δ-values will continue to be reported in the VSMOW/SLAP scale, using VSMOW2 and SLAP2 as calibration materials with their assigned stable isotope reference values.
