Stable Isotope Analysis Techniques: Powerful Analytical Tools for Various Fields
What Are Stable Isotope Techniques ？ A class of atoms with the same number of protons but different numbers of neutrons in the nucleus is called isotopes, which can be divided into stable isotopes and radioactive isotopes. The nucleus of a radioactive isotope is unstable, and it decays into another isotope by spontaneously emitting particles. Isotopes that are not radioactive are called stable isotopes. There are more than 1700 kinds of isotopes in nature, of which there are more than 270 kinds of stable isotopes. Compared with radioactive isotopes, stable isotopes have the advantages of safety, no pollution, and easy control. Stable isotope analysis is the premise of separation research, production and application, and it is an indispensable part of stable isotope science and technology. Analysis of stable isotopes can be performed by combining various analytical techniques such as mass spectrometry, gas chromatography, and liquid chromatography. Stable isotope techniques are use...
