Ana Racoveanu is a scientist synthesizing energetic compounds with isotopic labels, a rare feat in the nuclear security enterprise. Isotopic labeling uses various stable isotopes of given elements in ...

There are two fundamental ways to identify isotopic labels. The most direct method is mass spectrometry, in which a material is broken down into individual atoms or molecules, given electrical charge, ...

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 ...

(Nanowerk News) Isotope 'labeling' techniques replace specific atoms in a compound with an isotope that can be detected by its neutron count. For example, it may replace naturally-occurring carbon-12 ...

Isotope Ratio Mass Spectrometry (IRMS) has emerged as a critical analytical tool in the authentication of food products and the verification of their geographical origins. By precisely measuring the ...
