| Abstract: | Micellar electrokinetic capillary chromatography (MECC) of electric neutral compounds wasstudied on a 0.05mm i.d. x 450mm fused silica capillary tube with sodium dodecyl sulfate(SDS)solution and 254nm UV detection. In open-tubular capillary two phases, aqueous and micellar,move with different velocities and micellar solubilization operates as the distribution process ofsolutes. A novel mixed ethanol-water micellar solution was introduced to MECC of weak polarcompounds. The effects of electric field strength, concentration of SDS and ethanol content oncolumn efficency were examined. |
