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.
