“…This approach combines both partial and complete complexation modes and, thus, enables rapid, selective, efficient separation together with sensitive direct UV detection of metal species (Fig. 2) by precapillary derivatization is difficult because in this case only small differences in the ratio of charge to radius are observed, that result in nearly identical electrophoretic mobilities of these chelates [25,26,40].…”

This review gives a short overview of the main approaches to the derivatization of inorganic ions in capillary electrophoresis (CE) with emphasis on the most recent works. Various derivatization procedures and detection methods are discussed. A brief account of their advantages and limitations is given. More specific areas such as microchip CE, simultaneous separation of anions and cations, and speciation analysis are also briefly discussed.

“…For example, the contents of Ni, Co, and Cu in nickel ores were determined precisely using zinc as an internal standard [140]. Similar samples analyzed successfully by CE encompass RE ores [71,73] and geological standards [141], duralmin alloys [79], and platinum metal concentrates [75]. In an interesting application, Kelly and his group [142±144] systematically applied CE to study corrosion processes taking place in aircraft aluminum alloys.…”

Advances in the fundamental studies and methodology of capillary electrophoresis (CE) as applied to metal ion analysis over the last two years are reviewed, with the objective of providing the interested reader with a state-of-the-art picture of technique's potentialities in the area. In particular, novel strategies for separation selectivity control and CE system innovations designed to enhance the detection sensitivity are described. In addition, a brief overview of the primary metal analytes and samples for which the technique appears to be best suited is given. The current limitations of the technique regarding most of all the implementation for routine use are considered along with the approaches on how they could be addressed. Finally, some pointers as to the likely trends in the future research are discussed.

“…Some CE separations and determinations of transition-metal ions have also been reported using complexing agents, such as 8-hydroxyquinoline-5-sulfonic acid, 15 2-(5-bromo-2-pyridylazo)-5-(N-propyl-N-sulfopropylamino)phenol, 16 1,10-phenanthroline (phen) derivatives, 17 and xylenol orange. 18 Yokoyama et al 17 reported the separation of five metal ions (iron, cobalt, nickel, copper, and zinc) by CZE after complexation with phen.…”

“…18 Yokoyama et al 17 reported the separation of five metal ions (iron, cobalt, nickel, copper, and zinc) by CZE after complexation with phen. However, the complexation of these metal ions with phen was carried out by manual operation, and the complexation of vanadium with phen in the CZE has not been described.…”

An Alternative Interface for a Flow Injection-Capillary Electrophoresis System with Electrokinetic Injection

An alternative interface for flow injection-capillary electrophoresis based on electrokinetic injection is described. The interface basically consists of tubular platinum and a commercially available standard tee connector. The tubular platinum works as not only an electrode, but also a waste outlet of a split sample solution. The availability of the proposed interface is evaluated by the separation of several transition metals, such as vanadium, iron, and cobalt with 1,10-phenanthroline, and by the determination of iron in steel.
