Abstract:
The vacuum electro-spray ion source comprises a hollow capillary, a vacuum cavity, a gas inlet pipe, a gas supply device and an adjusting device, wherein a first end of the hollow capillary is a sampling port, and a second end is used as a spray nozzle for vacuum electro-sprays and stretches into the vacuum cavity; the air pressure in the vacuum cavity is ranged from 10 to 200 Pa; one end of the gas inlet pipe stretches into the vacuum cavity, and the other end is connected with the gas supply device; and the adjusting device is configured for adjusting the gas inlet pipe to allow the gas to flow therein intermittently. The ion source may achieve electro-spray ionization in the vacuum environment, so that losses during ion transmission may be reduced to improve the signal intensity and detection limit during detection.

Claim (Index 6):
The vacuum electro-spray ion source of  claim 1 , wherein a gas supplied by the gas supply device is helium.
