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 5):
The vacuum electro-spray ion source of  claim 2 , Wherein the gas inlet pipe further comprises a third hollow pipe and a silica gel collapsible hose; the adjusting device comprises a pinch valve; an end of the third hollow pipe is connected with an end of the second hollow pipe within the pinch valve via the silica gel collapsible hose, and the other end of the third hollow pipe is connected with the gas supply device, wherein the pinch valve is used for controlling the circulation of gas flows between the third hollow pipe and the second hollow pipe.
