Atmospheric pressure ionization mass spectrometer |
| abstract |
(57) [Object] To provide an atmospheric pressure ionization mass spectrometer capable of preventing the influence of a nonvolatile salt on mass spectrometry and preventing the vacuum of a mass spectrometry unit from being impaired in the prevention. A solution containing a non-volatile salt is supplied from a pump (1) to an LC. It is sent to the spray probe 4 for electrospray of the / MS interface, and is sprayed from the tip into the atmosphere 6 as fine droplets 5 having electric charge. The sample ions contained in the droplets are deflected by the deflector 7, enter the mass analyzer 22 from the ion sampling pore 17, and are subjected to mass analysis. On the other hand, the non-volatile salt goes straight without being affected by the deflector 7, collides with the wall of the particle collector 13 and is captured. The trapped salts precipitate as crystals, and the precipitated salts are washed away by the washing liquid from the washing nozzle 11. |
