Iron has four naturally occurring stable isotopes: 54Fe (5.85%), 56Fe (91.75%), 57Fe (2.12%) and 58Fe (0.28%) and its isotopic composition has been of interest since the invention of isotope ratio mass spectrometry. For example, Fe isotopes have been used to evaluate if extra-terrestrial Fe has the same isotope composition of terrestrial Fe (Valley and Anderson 1947), how Fe is cycled in the human body (Tang and Trassy 1986; Walczyk 1997), and the extent to which Fe is fractionated by geological processes (Beard and Johnson 1999; Bullen et al. 2001; Dixon et al. 1992). In this chapter, we discuss how Fe isotope analyses are conducted, with an emphasis on the methods used to ensure accurate Fe isotope analysis.
