DEVICE AND PROCESS FOR CONTINUOUS ON-CHIP FLOW INJECTION ANALYSIS

摘要

A micro-fluidic method for continuous pressure-driven flow injection analysis is described. The present invention comprises a planar microfluidic device intended for pressure driven flow injection analysis, whereupon a network of microchannels is imparted to allow a continuous flow of sample stream on the device, as well as facile and reproducible analyte plug injection to a reagent or buffer stream on microchip-based devices. The presented method allows for sequent separation analysis without additional purging cycles.
