Abstract
This invention provides a chip type micro nozzle, which is manufactured by molding in an integral formation fashion and can be used for analysis in the liquid phase mass spectrometer as it can produce electrically driven jet droplet. This invention further provides a manufacture method of the chip type micro nozzle. A polymeric material is used to manufacture the chip type micro nozzle by molding in an integral fashion, in which electrodes, micro ducts and micro nozzles are directly integrated into the chip to achieve the aim to eliminate the dead volume between the micro duct and the capillary and to increase stability of signal of mass spectrometer, which enables fast and precise sample analysis. The invented micro nozzle is applicable to mass spectrometric examination and analysis in biological, chemical and medical fields.
