“…They have presented methods for the separation of enantiomers in biological samples [76][77][78], inorganic ions in water samples [76,79], preservatives in food products [80] in beer and wine [81][82][83] and also in urine [84,85] as well as reports on the separation of proteins [86,87]. In nearly every case, only minimal sample pretreatment was required before analysis, thereby making these rapid and simple methods very attractive for routine analysis.…”

Poor sensitivity is considered to be one of the major limitations of electrophoretic separation methods, particularly when compared to traditional liquid chromatographic techniques. To address this issue, various in-line preconcentration techniques have been developed over the past 15 years, ranging in power and complexity, and there are now a number of well understood approaches routinely capable of providing a 10,000- to 100,000-fold increase in sensitivity, as well as several that can be pushed above a million. Furthermore, these have been achieved with particularly troublesome and often difficult samples, such as those having high salinity from a biological or environmental origin. This review will discuss the most common methods for improving the sensitivity of CE, CEC and microchip version of these, with particular attention to those approaches developed over the last five years.

“…All major anionic compounds could be determined and quantified in several different samples including red wine, white wine, beer, fruit juices and milk. This ITP and CZE were coupled in a microchip configuration called column-coupling chip that was used for the determination of total sulfite in wine samples [115]. Using this strategy, wine matrix could be eliminated and the analyte of interest concentrated to a certain extent.…”

“…These applications of microchips-CE include the analysis of DNA [64][65][66], proteins [110], amines [111], seleno-amino acids [112], antioxidants [113,114] and sulfite [115]. Besides, among the current developments in microchip-CE, different detection schemes have been developed to be used together with these microdevices.…”

“…The group of Kaniansky has continued to expand the technique of column coupling on a chip. While ITP-CE hyphenation has already been rectified for real-world applications [95,158], the feasibility study dealing with column switching in zone electrophoresis [159] revealed the major benefits associated with using the coupled channels. These are on-column sample clean-up and different separation mechanisms performed on the same chip.…”

The major methodological developments in CE related to inorganic analysis are overviewed. This is an update to a previous review article by the author (Timerbaev, A. R., Electrophoresis 2004, 25, 4008-4031) and it covers the review work and innovative research papers published between January 2004 and the first part of 2006. As was underlined in that review, a growing interest of analytical community in providing elemental speciation information found a sound response of the CE method developers. Presently, almost every second research paper in the field of interest deals with element species analysis, the use of inductively coupled plasma MS detection and biochemical applications being the topics of utmost research efforts. On the other hand, advances in general methodology traditionally centered on a CE system modernization for improvements in sensitivity and separation selectivity have attracted less attention over the review period. While there is no indication that inorganic ion applications would surpass by the developmental rate the more matured analysis of organic analytes, CE can now be seen as an analytical technique to be before long customary in a number of inorganic analysis arenas.
