Mass spectrometer |
| abstract |
An improved mass spectrometer and method of mass spectrometry are provided. A mass spectrometer is disclosed that includes an ion beam attenuator that attenuates an ion beam by repeatedly switching between a zero transmission mode of operation in period ΔT 1 and a non-zero transmission mode of operation in period ΔT 2 . The degree of attenuation of the ion beam can be changed by changing the mark space ratio ΔT 2 / ΔT 1 . An ion beam attenuator can emit ions in packets or pulses, but the ion packets or pulses are transmitted in a continuous ion beam by a relatively high pressure ion guide or gas collision cell located downstream of the ion beam attenuator. Can be converted to [Selection] Figure 6 |
