<p><b>Isotope fractionation</b> describes <a href="page.php?w=fractionation">fractionation</a> processes that affect the relative abundance of isotopes, a phenomenon that occurs (and so advantage is taken of it) in the study <a href="page.php?w=isotope_geochemistry">geochemistry</a>, biochemistry, food science,  and other fields. Normally, the focus is on <a href="page.php?w=stable_isotope">stable isotope</a>s of the same element. Isotopic fractionation can be measured by <a href="page.php?w=isotope_analysis">isotope analysis</a>, using <a href="page.php?w=isotope-ratio_mass_spectrometry">isotope-ratio mass spectrometry</a>,</p><p>
