Characterization of chemical selectivity in micellar electrokinetic chromatography VI. Effects of surfactant counter-ion
JOURNAL OF CHROMATOGRAPHY A, 888(1-2), 229–240.
author keywords: selectivity; linear solvation energy relationships; micellar electrokinetic chromatography; surfactants
MeSH headings : Chromatography, Micellar Electrokinetic Capillary / instrumentation; Sensitivity and Specificity; Surface-Active Agents / chemistry; Thermodynamics
TL;DR:
It was determined that selectivity differences are dependent on the valency of the counter-ion but not the type ofcounter-ion, and it is believed that the divalent counter-ions reduce the electrostatic repulsion between the surfactant head groups and therefore, increase the chain packing of the monomers in the micelle aggregates.

2000 journal article
Congeneric behavior in estimations of octanol-water partition coefficients by micellar electrokinetic chromatography
ANALYTICAL CHEMISTRY, 72(6), 1228–1235.
MeSH headings : Chromatography, Micellar Electrokinetic Capillary / methods; Hydrogen Bonding; Octanols / chemistry; Water / chemistry
TL;DR:
Linear Solvation Energy Relationships (LSERs) are used to explain the congeneric behavior observed when using Micellar Electrokinetic Chromatography (MEKC) to estimate the octanol-water partition coefficient scale of solute hydrophobicity.

2000 journal article
Influence of ester and amide-containing surfactant headgroups on selectivity in micellar electrokinetic chromatography
ELECTROPHORESIS, 21(12), 2390–2396.
author keywords: micellar electrokinetic chromatography; surfactant head-group; linear solvation relationships
TL;DR:
While both the solute size and hydrogen bond accepting ability were found to be the most important factors in solute retention, the hydrogen bonding characteristic of the solutes have the largest influence on selectivity differences between surfactants.

Statistical evaluation of linear solvation energy relationship models used to characterize chemical selectivity in micellar electrokinetic chromatography
JOURNAL OF CHROMATOGRAPHY A, 886(1-2), 245–257.
author keywords: linear solvation energy relationships; micellar electrokinetic chromatography; statistical analysis; surfactants
MeSH headings : Chromatography, Micellar Electrokinetic Capillary / methods; Models, Chemical
TL;DR:
The revised model and parameters have been found to yield a statistically better fit of the MEKC retention data as well as providing more chemically sound LSER coefficients.

Characterization of chemical selectivity in micellar electrokinetic chromatography. 4. Effect of surfactant headgroup
ANALYTICAL CHEMISTRY, 71(7), 1270–1277.
MeSH headings : Chromatography, Micellar Electrokinetic Capillary / methods; Hydrogen Bonding; Surface-Active Agents / chemistry
TL;DR:
The results suggest that the hydrogen-bond-accepting ability for surfactants is inversely proportional to the proton acidity of its headgroup.
