Isotope ratio measurements are indispensable for deciphering processes in geology, environmental science, and industrial chemistry. By quantifying the relative abundances of stable isotopes, these ...

The making of our moon, according to a widely accepted theory, took place billions of years ago when a giant planetary body called Theia collided with a nascent Earth, producing debris that eventually ...

Novae – explosions of white dwarf stars – are among the most frequent and violent events in our galaxy. They are thought to play a key role in synthesizing heavy elements, but the mechanisms behind ...

Astronomers at Leiden University have detected rare isotopes of carbon and oxygen in our neighboring stars for the first time, providing a new path toward better understanding the chemical evolution ...

Astronomers have counted the number of neutrons inside carbon atoms from 2.8 quadrillion km away. The team managed to measure the ratios of carbon isotopes in the atmosphere of an exoplanet for the ...

Isotopic analysis primarily involves the separation of isotopes based on the significant differences in mass. The method is effective for identifying the isotopic signature within the inorganic and ...

This GC-IRMS system is configured to perform compound-specific isotope analysis of compounds that are separable via gas chromatography, and can measure either δ 2 H or δ 13 C.

With the new grant, the Stable Isotope Lab will acquire a cutting-edge instrument called an isotope-ratio-monitoring mass spectrometer (IRMS). A major grant from the National Science Foundation (NSF) ...

This is a preview. Log in through your library . Abstract We investigated the effects of acid washing on the carbon and nitrogen composition and stable isotope ratios of C and N in shrimp (Metapenaeus ...

Although predicted some time ago, there has been little success in demonstrating that the overall fitness of migratory birds depends on the combined influences of their experiences over all seasons.
