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) ...

We measured δ¹³C of CO₂, CH₄, and acetate-methyl in profundal sediment of eutrophic Lake Dagow by incubation experiments in the presence and absence of methanogenic inhibitors chloroform, bromoethane ...

Archeologists and scientists analyze what are known as stable isotopes to date sites and artefacts. We made the following inforgraphic as an overview to help you understand more about what stable ...

Stable isotope techniques can help improve soil management and crop nutrition. To ensure the quality of stable isotope analysis through isotope ratio mass spectrometry (IRMS), appropriate sample ...

This publication contains four detailed technical papers on CO2 isotopes, CH4 isotopes, N2O isotopes, and air extraction from ice cores for isotope measurements. They are intended for both experienced ...

Responding to a lack of sensitive analytical methods for detecting associated medications in complex wastewater matrices, researchers at the University of Louisville developed and validated a liquid ...

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 ...

A team of Chinese researchers has successfully pinpointed the growth years of three ancient timbers in the Forbidden City and ...

I read George B. Kauffman’s article “Celebrating the Isotope” with great interest, as I did not know most of this history (C&EN, Dec. 2, 2013, page 30). However, there are some confusing statements in ...
