Cohn pioneered the use of isotopic tracers to examine the metabolism of sulfur-containing compounds.
2.
In theory, any element with two stable isotopes can be used as an isotopic tracer.
3.
Isotopic tracers are usually subdivided into two categories : stable isotope tracers and radiogenic isotope tracers.
4.
Further discussion of the application of isotopic tracers in geology is covered under the heading of isotope geochemistry.
5.
Isotopic tracers are some of the most important tools in geology because they can be used to understand complex mixing processes in earth systems.
6.
Chemical methods use the presence of relatively inert water-soluble substances, such as an isotopic tracer or chloride, moving through the soil, as deep drainage occurs.
7.
An " isotopic tracer ", ( also " isotopic marker " or " isotopic label " ), is used in chemistry and biochemistry to help understand chemical radioactive tracing ).
8.
The company, Isotag L . L . C ., has an isotopic tracer, a molecule that the company says can be mixed into liquids or gas during the manufacturing process without affecting its chemical makeup.
9.
Uses for uranium-233 include the production of medical isotopes actinium-225 and bismuth-213, low-mass nuclear reactors for space travel applications, use as an isotopic tracer, nuclear weapons research, and reactor fuel research including the thorium fuel cycle.
10.
This activity is suggested to account for a sudden rise in sulfate concentration observed near the base of the Cambrian; this can be recorded in the geochemical record both by using [ [ ?34S | ] ] isotopic tracers, and by quantifying the abundance of the sulfate mineral gypsum.
