MEEKC is an electrodriven separation technique that 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 oil droplets suspended in aqueous buffer, which is commonly referred to as oil-in-water ME. The droplets are stabilised by the presence of both 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 June 2008 - June 2010. Areas covered include online sample concentration, suppressed electroosmosis MEEKC, chiral separations, MEEKC-MS, MEEKC-ICP-MS and ME structure characterisation. The review also includes a fundamental introduction to MEEKC, along with a review of recent applications.
