Abstract: A micro-fluidic method for continuous pressure-driven flow injection analysis and a planar microfluidic device intended for pressure driven flow injection analysis are provided. A network of microchannels allows a continuous flow of sample stream on the devices, as well as facile and reproducible analyte plug injection to a reagent or buffer stream on microchip-based devices. The method allows for sequent separation analysis without additional purging cycles.
