Miniaturized device for sample processing and mass spectroscopic detection of liquid phase samples

摘要

A miniaturized planar device is described for use in a liquid phase analysis system. The device comprises a separation compartment that is in fluidic communication with a make-up flow channel and a channel compartment that terminates in a on-device mass spectrometer delivery means. The device is formed by microfabrication of microstructures in novel support substrates. The invention herein is used for the analysis of small and/or macromolecular and/or other solutes in the liquid phase. <IMAGE>
