The CUBES-SIL lab has three magnetic sector, gas-source, isotope ratio mass spectrometers designed to measure the relative abundance of stable isotopes of light elements and molecules. These ...

The stable isotope concentrations of a molecular compound or material are presented in ratio form as the molar ratio of the heavy-to-light isotopes. Since this ratio is small, we typically present ...

The Center for Isotope Geochemistry is a world-class facility for high-precision analysis of both radiogenic and stable isotopes on a wide range of materials. The Center is spread over two ...

Fractionation of the heavy and light stable isotopes is important because it a) produces variation in the stable isotope ratio of different element pools and b) establishes an isotope signal that can ...

Thermo MAT 253 Plus for high-precision, dual inlet analysis of multiply-substituted (“clumped”) isotopologues of CO2, with applications in geology, paleontology, oceanography and atmospheric sciences.

With standard single quadrupole GC/LC-MS, accurate detection of isotopic abundance is limited to ∼0.1 atom percent excess – equivalent to having 0.1% more heavy isotope than normal in the system.

Stable isotopes can also be used as tracers, which are deliberately added to a system that is to be studied, such as in agriculture or nutrition. For this purpose, they must be separated using highly ...

Stable isotope ratios vary among food webs and are incorporated into an animal's tissue via its diet (Hobson 1999). It is thus sometimes possible to infer the whereabouts of an animal moving ...

I have over 17 years’ research and commercial experience in the multi-disciplinary application of stable isotopes and in isotope ratio mass spectrometry (IRMS). My endeavours have produced multiple ...

Isotope ratios are measured using mass spectrometry, which separates out different isotopes and finds their relative abundance. Clumped isotope thermometry is a newer method that focuses on the ...
