Mass spectrometer |
摘要 |
A mass spectrometer is disclosed comprising a collision cell wherein ions having substantially different mass to charge ratios are arranged to be transmitted through at least a portion of the collision cell at substantially the same time and with substantially the same velocity preferably by means of one or more transient DC voltages or one or more transient DC voltage waveforms which are applied to the electrodes forming the collision cell so that ions are urged through the collision cell at a constant controlled velocity. By appropriate setting of the velocity of the DC voltage or DC voltage waveform passing along the length of the collision cell an efficient collision cell is provided which is able to fragment ions having considerably different mass to charge ratio at substantially the same time in an optimal manner.
