High Resolution Isotope Ratio MS

High Resolution Isotope Ratio MS



Discover a new world of mass spectrometry. The Thermo Scientific™ 253 Ultra™ high resolution isotope ratio mass spectrometer revolutionizes the measurement of site-specific and clumped-isotope-ratio analysis of intact molecules. Analysts now get direct access to the conditions under which

molecules were formed and how they were transported, stored, and degraded.

This will enable new discoveries inclimate research, biochemistry, forensics, oil, and gas exploration.


Gas Isotope Ratio MS

Gas Isotope Ratio MS



Measure isotopic signatures with extreme precision and sensitivity to provide the unique insight into the history and origin of compounds with Thermo Scientific isotope ratio mass spectrometry.

  • Combine all isotope ratio mass spectrometry (IRMS) applications in a single analyzer. The Thermo

Scientific™ Delta V™ IRMS systems combine outstanding sensitivity with excellent linearity and   stability to address applications as diverse as the detection of honey adulteration by EA-IRMS to δ13C analysis of PAHs in soil with GC-IRMS.

  • Get the highest sensitivity and precision for the determination of isotope ratios with the Thermo

Scientific™ MAT 253™ stable isotope ratio mass spectrometer. It provides a flexible and open

platform for the connection of inlet systems and preparation devices for the smallest amounts of sample in IRMS.
