摘要
Sodium decyl and dodecyl sulfates were evaluated as micellar phases for the micellar electrokinetic chromatographic separation of ASTM test mixture LC-79-2. Selectivity was similar in each system but different from the selectivity obtained in reversed-phase high-performance liquid chromatography. Despite separation efficiencies of approximately 150 000 theoretical plates per 50 cm, benzene and benzaldehyde coeluted in all concentrations of both surfactants employed. Separation was, however, readily achieved by addition of Brij 35® [polyoxyethylene(23)dodecanol] to the micellar phase. © 1990.
