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, frequent new innovations across the portfolio, and a commitment to a sustainable future, our isotope ratio mass spectrometers are the obvious choice for your analytical needs.
