The influence of convection on the structure of an isotachophoretic boundary is investigated using an asymptotic method to simplify the conservation equations. To illustrate the methodology it is applied to a simple strong electrolyte system consisting of three ions and the relevant equations solved numerically. The technique, however, is of general applicability and can be useful in exploring the influence of various flow processes on analytical and preparative electrophoretic separation techniques in addition to isotachophoresis.
