| Abstract: | By mixing 1H2O and 2H2O, both with accurately known purity, samples were prepared with 2H/1H ratios close to those of the international isotopic water standards: V-SMOW and SLAP. A mass spectrometrical comparison of these calibration samples with the actual water standards revealed:
2H/1H of V-SMOW = (155.95 ± 0.08) × 10?6
2H/1H of SLAP = (89.12 ± 0.07) × 10?6
δ2HV-SMOW(SLAP) =?428.5 ± 0.5 % |
