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.

Featured stable isotope ratio analysis applications

Reconstructing the climate of the past with the help of isotopes

Isotopic analysis of ice cores and biogenic carbonates can be linked to temperature and global sea level variations. Also, clumped-isotope thermometry is attracting growing interest as a very powerful tool for paleotemperature reconstructions. Read more about how gas IRMS technology is supporting climate research.

Getting unique information from complex compounds using isotopic signatures

Isotopic signatures in a wide variety of complex organic compounds can reveal unique insights in environmental, biological and (geo)chemical process, such as metabolism, diagenesis, degradation, environmental pollution and more. Read more about how gas IRMS technology is supporting these various fields of research.

How isotopes can help with food authenticity control

Isotopic analyses of foods have become a widespread tool to evaluate the quality, authenticity and origin of food products. See how IRMS technology is improving food quality.
