| Surfactants have played an important role in many sub-disciplines of separation science. In capillary electrophoresis (CE), they have been employed in a variety of aggregate formats (micelles, vesicles, liposomes, microemulsions, etc.) as a pseudostationary phase (PSP) for the separation of neutral or charged compounds with similar electrophoretic mobilities. In HPLC, surfactants have been employed predominantly as micellar mobile phases that have proven to be a useful alternative to the hydro-organic mobile phases routinely employed in reversed phase HPLC. Following an appropriate tribute and introduction, some recent advances are described w.r.t. the following subjects: 1. the improved electrokinetic chromatographic performance of novel chiral microemulsions formed from two or more chiral components (surfactant, co-surfactant, and/or oil) 2. the improved electrokinetic chromatographic performance of novel unilamellar vesicles formed from oppositely-charged, single-tailed surfactants. 3. the improved efficiency in micellar liquid chromatography (MLC) achieved by optimizing certain aspects of both stationary and mobile phase conditions. |
