isotope ratio mass spectrometry

In isotope ratio mass spectrometry (IRMS), element isotope ratios are determined very accurately and precisely. Typically, single focusing magnetic sector mass spectrometers with fixed multiple detectors (one per isotope) are used. Complex compounds are reduced to simple molecules prior to measurement, for example, organic compounds are combusted to CO2, H2O and N2.

The term "isotope ratio mass spectrometry" was found in the following pages:
