“…However, the micelle has a dynamic structure, 3 and the properties of the micelle, e.g., the critical micelle concentration (CMC), aggregation number, and micelle size, are strongly affected by the total concentration of the surfactant, pH, temperature, additives, and composition of the background solution. 4 Recently, high-molecular-mass surfactants (HMMSs) have been employed as pseudostationary phases in MEKC. [5][6][7][8][9][10][11][12][13][14] Since an HMMS forms a molecular micelle which consists of one molecule, and the CMC value is ideally zero, one can expect a higher repeatability in an HMMS-MEKC system compared to an LMMS-MEKC system.…”
