Primesep C separates a mixture of quaternary amines by a combination of cation exchange, complex formation, and hydrophic interactions. Methyltriethylammonium, tetraethylammonium, and tetramethylammonium cations as well as bromide counter ion are separated on a short 50 mm column. The separation uses a mobile phase mixture of water, acetonitrile (MeCN, ACN) and triethylamine acetate with evaporative light scattering detection (ELSD).
