“One [goal] was to look at the soil biology, see what is interacting with the phytate. The other was to explore and track oxygen isotopes in phytate using the Orbitrap IRMS.” The researchers incubated ...

A new study reveals that the aerobic nitrogen cycle in the ocean may have occurred about 100 million years before oxygen began to significantly accumulate in the atmosphere, based on nitrogen isotope ...

The neutron-rich oxygen isotopes oxygen-27 and oxygen-28 exist as very short-lived resonances, report scientists based on the first observation of their decay into oxygen-24 and three and four ...

A team of researchers says oxygen isotopes found in rock types contain the oldest geochemical record of the Earth. A collective understanding of five different data sets show that, all the way ...

AMES, Iowa – The Earth of 3.2 billion years ago was a “water world” of submerged continents, geologists say after analyzing oxygen isotope data from ancient ocean crust that’s now exposed on land in ...

Isotopes of hydrogen and oxygen can also be used to date and study the movements of water, since water is made up of these two elements. For example, by comparing the ratio of certain oxygen isotopes ...

The Global Network of Isotopes in Precipitation (GNIP) is a worldwide isotope monitoring network of hydrogen and oxygen isotopes in precipitation, initiated in 1960 by the International Atomic Energy ...

The paper, titled Distinct oxygen isotope compositions of the Earth and Moon, may challenge the current understanding of the formation of the Moon. Previous research led to scientists to develop ...

In 2024, we added a Thermo 253 Plus Isotope Ratio Mass Spectrometer which is dedicated to high precision analysis of nitrogen and oxygen isotope ratios of N 2 O using the denitrifier gas bench method.
