Self-assembled coating for modification of the electro-osmotic flow in nonaqueous capillary electrophoresis using formamide

Abstract: The use of pure nonaqueous solvents in capillary electrophoresis (CE) can alter the separation selectivity and enhance the solubility of hydrophobic compounds and enables the use of higher voltages. However, control of the electro-osmotic flow (EOF) is essential. In this work, we report the use of self-assembled coatings for EOF modification and elimination of analyte adsorptions onto silica capillaries in pure formamide. Bilayer capillary coatings derived from the double chain cationic surfactant dimethyldioc… Show more

“…2C 18 DAB is a double-chained synthetic surfactant that has frequently been used as a coating agent. [14][15][16][17] The structure of this surfactant resembles 2436 M. Zandkarimi et al phospholipids in a living cell membrane. Double-chained surfactants such as phospholipids or 2C 18 DAB form a flat, uniform, and semi-stable bilayer and make suitable coating agents.…”
