While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element ...

Sulfur isotopes can indicate a person’s proximity to the ocean. Isotopes of carbon and nitrogen, meanwhile, differ according to diet and can be particularly helpful in West-Central Africa ...

Certain chemical elements have more than one type of atom. Different atoms of the same element are called isotopes. Carbon has three main isotopes. They are carbon-12, carbon-13 and carbon-14.

China claims that it has achieved success in starting mass production of a radioactive isotope –Carbon-14, which has wide ranging uses in science and medicine. The mass production of carbon-14 ...

This measurement provides carbon, oxygen and “clumped” isotope ratios for carbonate minerals, which enables us to reconstruct the temperature at which the carbonate formed, along with information ...

Collagen was extracted and analyzed for bulk stable isotopes of carbon-13 (δ 13 C) and nitrogen-15 (δ 15 N) and compound-specific isotopes of individual amino acids. Radiocarbon dating provided ...

Stable isotope analysis of elements such as carbon, nitrogen and sulphur is used in ecology to trace the flow of nutrients through food webs and assess trophic levels.

ASP Isotopes (ASPI) announced that it has started commercial production of enriched Silicon-28 at its second Aerodynamic Separation Process, ...
