What is IRMS?

Isotope ratio mass spectrometry (IRMS) is the study of natural and synthetic samples based on their isotope ratios. The isotope ratio of a material will vary depending on its source and origin as well as on processes that may occur during the lifetime of that material. While IRMS is widely used in Earth sciences to understand Earth’s geological history, it is also used in food authenticity, forensics, medical research, and antidoping testing.

We offer a comprehensive portfolio of isotope ratio mass spectrometers. With more than 70 years of experience building cutting edge analytic instrumentation and with frequent new innovations across the portfolio, our isotope ratio mass spectrometers are the obvious choice for your analytical needs.

Understanding the world around us and our place within it using isotopes.
From demise of the dinosaurs through to finding new ways to diagnose diseases, isotope research provides critical information about biological, chemical and geological processes. Isotopes can be used to provide information on how ancient civilizations lived, they can be used to date critical events in the geological past and can provide insights into disease pathways. Explore the ways that isotopes can benefit your field of research.
