Misha lived her whole life in zoos, but this elephant's teeth are now helping scientists reconstruct wildlife migrations. Geologists show how strontium isotopes found in teeth or tusks reveal where ...

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 ...

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

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 ...

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.

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% ...

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% ...

For large plant-eating land mammals, the relative abundance of two strontium isotopes in teeth and tusks reflects where the creature may have roamed during its lifetime. “Our study not only adds ...
