Abstract:
An integrated chemical analysis system, comprising:a first substrate having a major surface; a second substrate bonded to or otherwise attached to said first substrate; a liquid chromatography system integrated in said second substrate, and configured to receive a fluid for analysis and to process and output the fluid; and a monolithic electrospray device having an entrance orifice on an injection side and a nozzle on an ejection surface on an opposite planar side from the injection side, a channel extending continuously through the monolithic device in communication with the entrance orifice and the nozzle, and a region surrounding the nozzle recessed from the ejection surface, wherein said monolithic device is integrated on said first substrate, the injection side configured to receive the processed fluid from the liquid chromatography system, the major surface being configured to dispense the fluid by electrospraying the fluid.
