Patent ID: 8794551

Claim:
A microfabricated multiplex system for electrospraying an electrosprayable fluid to produce droplets of essentially uniform size from multiple conejets from an integral array of substantially uniform nozzles, the system comprising: a) an integral array of substantially uniform nozzles capable of producing droplets of essentially uniform size from multiple conejets, said multiple conejets produced when a liquid is fed through each of the array of substantially uniform nozzles and a liquid meniscus at an outlet of each of the substantially uniform nozzles forms a conical shape under an action of an electrical field with a thin jet emerging from the cone tip that breaks up into a spray of fine, charged droplets; b) at least one extractor electrode array positionable at a distance from the top of the array of nozzles; c) a source of fluid operably connected to the array of substantially uniform nozzles for providing the fluid to be electrosprayed; and d) electrical means for maintaining a desired voltage drop between the array of substantially uniform nozzles and the at least one extractor electrode array.
