Tetramethylammonium chloride is a quaternary ammonium salt used widely as a reagent in industrial applications. It can be separated from sodium and potassium chlorides on a mixed-mode Newcrom AH column with a simple isocratic MS-compatible mobile phase of water, acetonitrile (ACN) and ammonium formate (AmFm) buffer.
