ELECTROSPRAY ION GENERATION WITH STIMULATION

摘要

An electrospray ionization device comprises a tip of a capillary tube (1) arranged in a chamber (5) and being adopted for injecting a sample solution into the chamber (5). A high voltage source (16) adopted for generating a first electrical field between a tip (4) of the capillary tube (1) and a first area of said chamber (5) is provided. The device comprises a generator (15) adopted for generating an alternating signal with a frequency of at least 10 kHz. The generator (15) is coupled to the capillary tube (1) for stimulating the generation of ion droplets out of the injected sample solution in response to generated pulses.
