Describing chemical transformations in multiple spiking isotope dilution: Fundamental aspects and definitions
Abstract
Currently, several mathematical methods exist to address simultaneous species formation and degradation using multiple spiking isotope dilution mass spectrometry. While all of these strategies have been compared numerically, comparison of the underlying principles is lacking. Owing to recent interest in using the species inter-conversion factors, mainly to study the quality of analytical methods, this manuscript reviews the mathematical logic and inconsistencies of the existing double or triple spiking isotope dilution models. Systematic terminology is also introduced to clarify the species inter-conversion coefficient definitions. © The Royal Society of Chemistry.
