Isotopic Analysis

Isotopes are different types of atoms of the same chemical element, each having a different atomic mass. Isotopes of an element have nuclei with the same number of protons but different numbers of neutrons.

Isotope analysis is the identification of isotopic signature, the distribution of certain isotopes within chemical compounds.

Isotope ratio mass spectrometry is a specialization of mass spectrometry, in which mass spectrometric methods are used to measure the relative abundance of isotopes in a given sample.
