and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element. For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written ...

oxygen and “clumped” isotope ratios for carbonate minerals, which enables us to reconstruct the temperature at which the carbonate formed, along with information about carbon cycle changes and ...

These TIMS’ were installed in 2016 and 2022 and are primarily used for high-precision analysis of small sample size neodymium and strontium isotopes on materials spanning the earth and environmental ...

Stable isotope amino acid tracers have been pivotal in understanding muscle protein synthesis and breakdown, helping reveal ...

Stable isotopes can be used by measuring their amounts and proportions in samples, for example in water samples. Naturally-occurring stable isotopes of water and other substances are used to trace the ...
