As a result, in 1984, micellar electrokinetic capillary chromatography (MEKC) was developed to separate neutral compounds [2]. This separation is achieved by the addition of ionic micelles to the electrophoretic medium.

Micellar electrokinetic chromatography (MEKC) is a chromatography technique used in analytical chemistry. It is a modification of capillary electrophoresis (CE), extending its functionality to neutral analytes, where the samples are separated by differential partitioning between micelles (pseudo-stationary phase) and a … Visa mer The micelle velocity is defined by: $${\displaystyle u_{c}=u_{p}+u_{o}}$$ where $${\displaystyle u_{p}}$$ is the electrophoretic velocity of a micelle. The retention time of a given sample should depend on … Visa mer The simplicity and efficiency of MEKC have made it an attractive technique for a variety of applications. Further improvements can be made to the selectivity of MEKC … Visa mer • Kealey, D.;Haines P.J.; instant notes, Analytical Chemistry page 182-188 Visa mer WebbEKC is based on chromatographic principles using homogeneous solutions containing an ionic “carrier” and the same apparatus as CE. The unique … WebbMixed-mode chromatography. Mixed-mode chromatography (MMC), or multimodal chromatography, refers to chromatographic methods that utilize more than one form of interaction between the stationary phase and analytes in order to achieve their separation.
