WebIn contrast, isotopes of varying mass produce multiple mass isotopomers B that are detected using mass spectrometry. The analysis demonstrates that the rate of synthesis of B is identifiable from stable isotope data but not from radioisotope data. This results because the isotopomer distribution of B at any time after tracer addition is a ... WebDefinition. Iron has four naturally occurring stable isotopes: 54 Fe, 56 Fe, 57 Fe, and 58 Fe of respective abundances 5.80%, 91.72%, 2.20%, and 0.28%. They are increasingly used to determine the source of the iron present in geological or biological materials and/or to characterize the chemical reactions that may have lead to the form of iron ...
