Abstract

An extension to the established methods for analysing an unknown sample by isotope dilution mass spectrometry (IDMS) is proposed. The new method simplifies the presentation of established methods by introducing the 'isotope dilution curve'. This shows how a method can be developed that does not require the measurement of the isotope ratio of the highly enriched spike and therefore limits the range of isotope ratios that have to be measured accurately.
