This was called high pressure liquid chromatography, or HPLC. ... High performance liquid chromatography is now one of the most powerful tools in analytical chemistry. It has the ability to separate, identify, and quantitate the compounds that are present in any sample that can be dissolved in a liquid.
Tetraethylammonium (TEA) is a simple quaternary ammonium compound. It is primarily used experimentally to block potassium channels Hille (2001). ... TEA also either mimics or antagonizes the actions of other quaternary ammonium ions, including choline and acetylcholine.
Tetraethylammonium(TEA) is synthesized from bromopentacarbonylrhenium by heating it with tetraethylammonium bromide in diglyme. It is a potassium-selective ion channel blocker.
Tetraethylammonium tetrafluoroborate is used as a phase transfer catalyst in organic synthesis. It finds application as an electrolyte additive in the capillary electrophoretic separation of polyphenols found in grape seed extracts. ... It is involved in the synthesis of conducting poly(thiophenes).
