Use of a fluorosurfactant in micellar electrokinetic capillary chromatography
Journal of Chromatography A, 2001 A fluorosurfactant, the anionic N-ethyl-N-[(heptadecafluorooctyl)sulfonyl]glycine potassium salt, trade name FC-129 [CAS 2991-51-7] was investigated for possible application in micellar electrokinetic capillary chromatography (MEKC). The surfactant was characterized with conductometric titration and test sample mixtures were investigated in MEKC ...

Electrokinetic Chromatography-based Micro Methods for Separation and Physiochemical Characterization of Very Hydrophobic Pharmaceuticals. [PDF]
J Sep SciABSTRACT This study established an efficient separation of the highly hydrophobic analytes fenofibrate, orlistat, lumefantrine and a micelle marker using microemulsion electrokinetic capillary chromatography. A starting buffer with sodium dodecyl sulphate, heptane and butan‐1‐ol resulted in a partial separation of the analytes.
