Summary Capillary electrophoresis of the quaternary ammonium ion herbicides, paraquat, diquat and difenzoquat was studied. Electrolyte running solutions with different alkaline salts were used to reduce adsorption of the solutes on the capillary wall. The influence of pH, temperature, applied voltage, buffer cation and injection mode was investigated. The results are discussed in terms of separation parameters such as migration time, apparent mobility, plate height and resolution. In addition, improvement of sensitivity related to the migration velocity and injection mode was observed. Resolution of paraquat and diquat was critical and required well-established conditions.
