Abstract (en)
[origin: EP0822574A1] The mass spectrometer has an ion source (21), a reflector (33), and a detector (34). There is a collision cell (22) containing an impurity gas, in which primary ions are fractured to produce fragment ions by collision with the impurity atoms or molecules. Each of several different pressure regions of the mass spectrometer has a vacuum pump connection (6,7,8). The regions are connected via the gas flow impedances (4,5,32). One region is a reflector chamber (3) containing the reflector. A further region is a scattering chamber (2) containing the collision cell, which is arranged before the reflector chamber in the ion flight direction.
