Abstract
A technique for separating, identifying and measuring ions in solution by capillary zone electrophoresis is described, which provides improved sensitivity and resolution of anionic species. The method involves subjecting a sample containing the ionic species a light-absorbing material and a quaternary ammonium salt to an electrical current in a capillary column causing the ions to elute according to their ionic mobility. The ionic species are detected and quantitated by UV/Visible photometric monitoring.
