“…The content of organic solvent could be added up to 45%. A typical comparison between polymeric micelles and normal micelle was reported by Otsuka, Wada, Ishisaka, and Terabe (2002). Poly (sodium 10-undecylenyl sulfate) micelles could tolerate 60% acetonitrile but SDS micelles could not when separating 11 kinds of PAHs.…”

“…Degree of polymerization was estimated to be from 3 to 9. Performance of each oligomer was briefly investigated in comparison with that in SDS-MEKC for the separation of components in cold medicine [33] and hydrophobic compounds or PAHs, which were used as test analytes [34].…”

Although electrochromatography in packed beds or monolithic columns has gained enormous interest, techniques based on charged pseudostationary phases like micelles are of high practical importance in electrically driven separation science. However, nonmicellar alternatives, e.g., using charged soluble polymers or smaller additives are still attractive, as they allow high concentrations of organic solvents, and their application is not limited by the critical micellar concentration. This review discusses the developments in the field of electrokinetic chromatography with these additives in the last three years, covering ionic polymeric pseudostationary phases, dendrimers and so-called micelle polymers, but also small molecules which implement separation selectivity due to their specific interaction with the analytes.

“…One of the most interesting ways to solve these problems is to use polymeric surfactants. The advantages of the last one are based in the fact that the theoretical Critical Micellar Concentration (CMC) is zero and the equilibrium micelle-surfactant is diminished [6][7][8] . Moreover, polymeric surfactants are more stable in presence of organic solvent due to the presence of covalent linkage between the unimers and because of their high molar mass can be conveniently used in MEKC-MS applications without background interference from monomer surfactantes of low molecular weights [9][10][11] .…”

“…a) polymerized micelles, b) dendrimers, and c) ionic polymers [13][14][15] . One of the most succefull polymers used as pseudostationary for separate a wide range of neutral analytes in MEKC is poly(sodium 10-undecylenate) (PSU) [16][17][18][19] . However, despite this, there is not systematic studies that relate the molar mass and hydrodynamic radius with the separation capacity of the PUS.…”

In this work we reported the synthesis of different molar mass fraction of poly(sodium-10-undecylenate) (PSU), and its subsequent utilization as pseudostationary phase in the separation of a mix of 4 polyaromatic hydrocarbons (PAHs); naphthalene (NAPH), fluorene (FLU), phenantrene (PHEN) and pyrene (PYR). Concentration and molar mass fraction of PSU were the main variable studied. The analytical parameters; efficiency (N), selectivity (α), and resolution (R s ) were calculated to assess the separation capacity. The best conditions for the separation were achieved using a buffer composed by 12.5 mM of each sodium borate and sodium hydrogen phosphate, yielding pH 9.2 in ACN/H 2 O (40/60) solvent, using PSU of molar mass fraction 30-50 kDa in concentration of 0.25 g 100 mL -1 . The applied voltage was 25 kV. Finally, Limit of Detection (LOD) and Limit of Quantification (LOQ) for 4 PAHs were calculated from the calibration curves in optimal separation conditions.
