      abstract     = {Capillary electrophoresis based on non-aqueous solvent
                      background electrolytes was employed, with single and
                      multiple wavelength UV detection, to evaluate discrimination
                      among oligomer components of mixtures of non-ionic, long
                      chain nonylphenol ethoxylates (NPnEO, with n = number of
                      ethoxy units) and their lipophilic degradation products. The
                      tested organic solvents included acetonitrile, methanol,
                      ethanol, 1- and 2-propanol, 1-butanol and tetrahydrofurane
                      in the presence of sodium acetate. A rational variation of
                      composition of background electrolyte solvent mixtures
                      allowed to modify the mobility of electroosmotic flow and
                      the type and degree of interactions between the ionic
                      additive (sodium acetate) and the components of the analyte
                      mixtures. The physicochemical properties of the solvents,
                      such as dielectric constant, viscosity and electron
                      donor-acceptor ability regarding the additive, were
                      considered to improve the resolution of lipophilic compounds
                      with less than three ethoxy groups and the discrimination
                      attainable for longer chain oligomers. The studied
                      methodologies also allowed discerning between surfactants of
                      similar (nominal) ethoxy chain lengths. This was
                      demonstrated by the different peak distribution patterns
                      observed for NPnEO compounds with n = 7.5 and 10,
                      respectively.},
