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. ==Properties== PFTs are believed non-toxic and chemically inert, clear, colourless liquids. They are non-flammable and are not radioactive. They do not occur in nature at all, so background levels are very low, but they can be detected at extremely low concentrations. There is a range of PFTs available commercially, allowing the experimenter to release different PFTs at the same time. Cyclic perfluorocarbons, such as perfluoromethylhexane and perfluoro-1,3-dimethylcyclohexane, are generally believed to be better than acyclic ones as they can be detected at lower levels. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Perfluorocarbon tracer」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
