| 英文摘要 | influences of seven organic modifiers, including urea, methanol (meoh), dioxane (dio), tetrahydrofuran (thf), acetonitrile (acn), 1-propanol (1-proh) and 2-propanol (2-proh), on the solute retention and the electrokinetic migrations in micellar electrokinetic capillary chromatography (mekc) are investigated with sodium dodecyl sulfate (sds) micelle as pseudostationary phase. it is observed that in the limited concentration ranges used in the mekc systems the effect of organic modifier concentration on the retention can be described by the equation logk'=logk'(w)-sc for most binary aqueous-organic buffer, but deviations from this retention equation are observed at acn and particularly thf as organic modifiers. with parameter s as a measure of the elutropic strength, the elutropic strength of the organic modifiers is found to follow a general order urea |
