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.
This term is used to describe the operation of the [[Mass Spectrometer]] in which the intensities of several specific ion beams are recorded rather than the entire [Mass Spectrum]]. An alternative recommended term is multiple ion (peak) monitoring. The use of the terms ????????????????????????multiple ion detection?????????????????????? and 'mass fragmentography' is not recommended.

Orange Book Entry

This term is used to describe the operation of the Mass Spectrometer in which the intensities of several specific ion beams are recorded rather than the entire [Mass Spectrum]]. An alternative recommended term is multiple ion (peak) monitoring. The use of the terms ????????????????????????multiple ion detection?????????????????????? and 'mass fragmentography' is not recommended.
