This article reviews the development of a thin-layer electrolysis cell with both a thin aqueous phase and a thin organic phase for ion transfer at the liquid|liquid interface for the absolute determination of a redox-inactive ion. In particular, an improvement of the cell performance by using a conducting polymer-coated electrode in the organic phase is discussed. The applicability of the thin-layer electrolysis cell to the absolute determination of redox-inactive ions using the flow-injection method or stripping method is also described.
