Momentum spectrum

A spectrum that is obtained when a beam of ions is separated according to the momentum/charge ratios of the ionic species contained within it. A sector magnetic field achieves separation of the various ionic species in this way. If the ion beam is homogeneous in translational energy, as is the case with sector instruments, separation according to the m/z Ratios is also achieved and a mass spectrum produced.
