| titleOfInvention | A kind of vacuum electric spray ion source and mass spectrograph |
| abstract | The invention discloses a kind of vacuum electric spray ion source and mass spectrographs.Vacuum electric spray ion source includes capillary hollow, vacuum cavity, air inlet pipe, feeder and regulating device, the first end of the capillary hollow is sampling port, spray head of the second end as vacuum electron spray, is protruded into the vacuum cavity, and the air pressure in the vacuum cavity is 10 ‑4 In the range of~200Pa；One end of the air inlet pipe is protruded into the vacuum cavity, and the other end is connected with feeder；The regulating device intermittently flows through gas for adjusting in the air inlet pipe.Ion source of the invention can realize electrospray ionisation under vacuum conditions.The vacuum cavity of vacuum electric spray ion source is connected to mass spectrometric vacuum cavity constitutes mass spectrograph, can reduce the loss in ion transmission process, improves signal strength and detection limit when detection. |
