Micro fluid chip for electro-spray ionization, has an electro-vapor structure as a pen nib with a capillary slot to tip and an electrode to apply a voltage to vaporize sample

摘要

The micro fluid chip (10), for electro-spray ionization (ESI), has an electro-vapor structure (1) with at least one flat and thin point (3) with a capillary slot (4) at the end (5) of the point, with the structure of a pen nib, to eject the liquid to be vaporized. The micro-fluid channel (11) in the chip has an outlet (12) which opens into the capillary slot. The assembly applies a voltage to vaporize the liquid.
