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 ...

Misha lived her whole life in zoos, but this elephant’s teeth are now helping scientists reconstruct wildlife migrations.

This variation in the relative abundance of stable isotopes results from tiny mass differences that cause the isotopes to act differently in chemical reactions and physical processes. The lighter ...

Chlorine naturally exists as two isotopes, \(_{17}^{35}\textrm{Cl}\) (chlorine-35) and \(_{17}^{37}\textrm{Cl}\) (chlorine-37). The abundance of chlorine-35 is 75% ...

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.

Carly Buchwald’s group uses the abundance stable isotopes of N and O in nitrite and nitrate to interpret nitrogen biogeochemistry in the environment. They measure the isotope systematics of relevant ...

Teeth recovered from a beloved zoo elephant that died in 2008 are helping University of Utah geologists develop a method for ...
