The modern electronic industry has played a very important role in the development of instrumentation based on physical-analytical methods As a result, a rapid boom in the fields of infrared, nuclear magnetic resonance (NMR), Raman, and mass spectroscopy and vapor-phase (or gas-liquid) chromatography has been observed. Instruments for these methods have become indispensable tools in the analytical treatment of fluonnated mixtures, complexes, and compounds The detailed applications of the instrumentation are covered later in this chapter.

Other purification methods include a liquid phase chromatography, electrophoretic separation by mass spectroscopy, separation using magnetic properties, and so on. These separation methods are limited only for the metal nanoparticles having a special property useful for these purification methods.

Research in the areas of high temperature chemistry, fluorine chemistry, optical and mass spectroscopy and thermodynamics has been supported at Rice University by the United States Atomic Energy Commission, by the US. Army Research Office (Durham), by the National Aeronautics and Space Administration, by the Petroleum Research Fund of the American Chemical Society and by the Robert A. Welch Foundation. Liquid helium for low temperature nock was provided through arrangements with the U.S. offices of Naval Research. 

The dialkylaminotellurium(VI) pentafluorides are pale yellow liquids that decompose rapidly above 35°C. Bis(dimethylamino)tellurium(VI) tetrafluoride is a pale yellow solid, mp 57°C. The compounds have been characterized by IR, Raman, H-NMR, 19F-NMR, and mass spectroscopy. Reaction of (RaSi)2NH with TeF6 produces RaSiNHTeF5 (mp 9°C), which can be cleaved with HF to yield aminotellurium(VI) penta-fluoride (155) [Eq. (14)].

The ELISA can be used as one component of a battery of analyses. Rarely is only one method used in isolation. Other tests include chromatographic methods such as reversed-phase high-performance liquid chromatography (HPLC), size exclusion chromatography, and physical structure analytical methods such as UV spectral analysis, mass spectroscopy, etc.
