Coupling Miniaturized Free-Flow Electrophoresis to Mass Spectrometry via a Multi-Emitter ESI Interface

Abstract

We present a novel multi-emitter electrospray ionization interface for the coupling of microfluidic<br>free-flow electrophoresis (μFFE) with mass spectrometry. 15 sample streams coming from 15 μFFE outlets were continuously analyzed in quick succession to monitor the electrophoretic<br>separation in the microchip.
