## Abstract Micellar electrokinetic chromatography (MEKC) allows the calculation of distribution coefficients between a micelle and the surrounding aqueous phase from the measurement of the migration time, provided the critical micelle concentration (CMC) and the phase ratio are known. Thermodynami
Properties of a binary mixed surfactant system of a nonionic surfactant, octylglucoside, and an anionic one, sodium dodecyl sulfate, were investigated by measurement of the surface tension of their aqueous solutions containing 20, 75, and 150 mM sodium chloride. Changes in the critical micelle conce
## Abstract Various tetraalkylammonium ions, such as tetramethylβ, tetrapropylβ, tetrapentylβ, and cetyltrimethylammonium, can be added to sodium dodecyl sulfate (SDS) micellar solutions to achieve unique selectivities in micellar electrokinetic chromatography (MEKC). The cetyltrimethylammonium/SDS
## Abstract In micellar electrokinetic capillary chromatography (MECC) the most widely used surfactant for the pseudostationary phase is sodium dodecyl sulfate (SDS), although other types of surfactants have been investigated. We have synthesized the magnesium salt of dodecyl sulfate (Mg(DS)~2~) in
