Stable Isotope Analysis

What the light stable isotopes can tell you

The analysis of the stable isotopes of hydrogen, carbon, oxygen, nitrogen and sulfur has widespread applicability in the natural sciences. The natural variations in the relative abundances of these isotopes can provide useful information in a wide variety of applications, such as forensics, food authenticity, environmental and paleoclimate research.
