In 2024, we added a Thermo 253 Plus Isotope Ratio Mass Spectrometer which is dedicated to high precision analysis of nitrogen and oxygen isotope ratios of N 2 O using the denitrifier gas bench method.

The CUBES-SIL lab has three magnetic sector, gas-source, isotope ratio ... oxygen and “clumped” isotope ratios for carbonate minerals, which enables us to reconstruct the temperature at which the ...

Oxygen was the first stable isotope used to determine migratory history in marine environments. Stable isotope analyses using marine oxygen have used barnacle shells attached to the study animal.
