Stored waveform inverse Fourier transform (SWIFT) |
---|
Technique to create excitation waveforms for ions in Fourier transform-ion cyclotron resonance-mass spectrometers or Paul ion traps. An excitation waveform in the time-domain is generated by taking the inverse Fourier transform of an appropriate frequency-domain programmed excitation spectrum, in which the resonance frequencies of ions to be excited are included.
