The high-performance preconcentration method is one of the most important techniques for the ultratrace component analysis. Especially, it can greatly improve the sensitivity and the precision of instrumental analysis. In this study, a homogeneous liquid-liquid extraction method with a perfluoro surfactant was attempted to become available as a preconcentration system for instrumental analysis. Thus, the fundamentals of the phase-separation phenomenon were investigated, and this homogeneous liquid-liquid extraction was applied to capillary electrophoresis (CE) as a preconcentration system. Moreover, an ultra-powerful preconcentration method exceeding ten-million-fold preconcentration was proposed by combining with this homogeneous liquid-liquid extraction method and other different kinds of preconcentration techniques. Environmental and biological analyses have to precisely measure by the reliable analytical method. In this study, new preconcentration and separation methods were created for the purpose of understanding the actual conditions of trace chemical species. Moreover, the presented concepts were applied to not only powerful preconcentration, but also separation and isolation. These approaches could solve serious problems (e.g. sensitivization, selective separation, simple procedure, cost, etc).
