Beschreibung
Zusammenfassung:	An electrospray device (100), a liquid chromatography device and an electrospray-liquid chromatography system are disclosed. The electrospray device (100) includes a substrate (102) defining a channel (104) between an entrance orifice (106) on an injection surface (108) and an exit orifice on an ejection surface (112), a nozzle (110) defined by a portion recessed (114) from the ejection surface (112) surrounding the exit orifice, and an electrode for application of an electric potential to the substrate (102) to optimize and generate an electrospray. The invention further provides a method for generating an electrospray of a fluid, with the said electrospray device, ejects the fluid from the channel through the nozzle by applying or holding the extracting electrode at a second potential voltage different from the first potential voltage.
