MEEKC is an electrodriven separation technique, which utilises the unique properties of a microemulsion (ME) as a background electrolyte to achieve separation of a diverse range of solutes. MEs are composed of nanometre sized on droplets suspended in aqueous buffer, which is commonly referred to as all oil-in-water ME The droplets are stabilised by the presence of a surfactant and co-surfactant The use of water-in-oil MEs in MEEKC has also been investigated This review details the advances in MEEKC-based separations from the period 2008 to 2009 Areas covered include online sample concentration, Suppressed electroosmosis MEEKC, chiral separation, MEEKC-MS, and structure-migration relationships The review also includes a Fundamental introduction to MEEKC, along with the presentation of recent applications
