Space charge control in a tandem ion trapping arrangement |
| abstract |
A mass spectrometer is disclosed comprising a first high capacity storage ion trap 2 arranged upstream of a high performance analytical ion trap 3. According to an embodiment ions are simultaneously scanned from both the first and second ion trap 2 and 3. At any instant in time the quantity of charge present within the second ion trap 3 is limited or restricted so that the second ion trap 3 does not suffer from space charge saturation effects and hence the performance of the second ion trap 3 is not degraded. Preferably ions are mass selectively ejected from both the first and second ion traps. Alternatively, ions may be attenuated as they are being transmitted from the first ion trap 2 to the second ion trap 3. |
