English Abstract

A mass spectrometer is disclosed comprising a
collision cell 1. Ions having substantially different
mass to charge ratios are arranged to be transmitted
through at least a portion of the collision cell 1 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 2
forming the collision cell 1 so that ions are urged
through the collision cell 1 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 1 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.
