Planet Isotopes

Do you want to find out more about the Thermo Scientific product portfolio for isotope analysis? Are you interested in a particular application? Do you want to learn more about the technologies for measuring isotopic and elemental abundances? Or do you want to explore the use of isotopes for a variety of applications? If so, you have come to the right place.


The analysis of the isotopic and elemental signatures of a certain material is challenging and requires state-of-the-art technology, as variations in isotope ratios are very small and most of the elements are only available in trace amounts. Visit our Technology pages for more information.


The Thermo Scientific isotope ratio analysis product portfolio enables precise and accurate detection of isotope ratios and analysis of trace elements in a wide variety of samples. Visit our Products pages for more information.


Isotope Ratio Mass Spectrometry is widely applied in Science and Technology touching the lives of all of us, such as climate research, food, forensics, geology, biology, hydrology, medical and environmental sciences, and many more. Visit the Applications pages for more information.
