Isotachophoresis

A nonlinear electrophoretic technique used to separate a variety of ionic compounds, ranging from small metal ions to large molecules like proteins. Unlike linear zone electrophoresis in which separating solute bands continually spread by diffusion or dispersion, isotachophoresis forms self-sharpening, adjacent zones of substantially pure solute whose concentrations often exceed several mgs/ml. In isotachophoresis a multianalyte sample is introduced between the leading electrolyte and the terminating electrolyte where the sample ions have lower electrophoretic mobilities than the leading ion but larger than the terminating ion.
