The precision is far higher than the accuracy, so that subtle isotopic differences must be made relative to a reference. Modern mass spectrometers can routinely measure the δ18O value of a gas with a precision of 0.01‰. This is 20 times more precise than the accuracy of the 18O/16O ratio of VSMOW (Baertschi 1976). It is for this reason that isotope analyses, like most analytical measurements, are reported relative to standards. The problem faced by the stable isotope community is that different materials are measured using...
