Reference Sheet: SLAP2
SLAP2 (Standard Light Antarctic Precipitation 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 SLAP material. SLAP2 was mixed from several carefully calibrated natural water samples from the Antarctic in order to obtain a stable isotope composition as similar as possible to the original SLAP. Three selected laboratories provided calibration measurements in direct comparison to SLAP. 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.
