  7. Perfluorocarbon tracer - Wikipedia

    en.wikipedia.org/wiki/Perfluorocarbon_tracer

    Perfluorocarbon tracers (PFTs) are a range of perfluorocarbons used in flow tracers and other tracing applications. They are used by releasing the PFT at a certain point, and determining the concentration of that PFT at another set of points, allowing the flow from the source to the points to be determined.
