Using isotopic measurements
Analyses isotopiques. Applications

Figure 2 presents the applications of isotopic measurements on elements or molecules, of natural or modified isotopic composition, in four groups [1] .

• In the transport phenomena monitoring group, the method consists of following an element, identifiable by one of its isotopes, along physical or chemical transformations. The isotope of this element with a content different from normal is called the tracer, or indicator. For certain applications, it is sufficient to be able to identify the tracer despite inevitable dilutions or isotopic...
