Abstract

The continuous separation mechanism of micro free-flow electrophoresis (μFFE) is a straightforward, suitable tool for microscale purification of reaction mixtures. However, aqueous separation buffers and organic reaction solvents limit the applicability of this promising combination. Herein, we have explored nonaqueous micro free-flow electrophoresis for this purpose and present its suitability for a continuous workup of organic reactions performed in acetonitrile. After successful nonaqueous FFE separation of organic dyes, the approach was applied to continuously recover the photocatalyst [Ru(bpy)
