The Characterization of Cationic Pseudostationary Phases for Electrokinetic Chromatography
Micellar electrokinetic chromatography (MEKC) and linear solvation energy relationships (LSER) have been used to characterize the solute distribution between water and self-assemblies formed from cationic surfactants containing systematic variations in structure. One series of surfactants consisted …
