This term is used to describe the operation of the @[email protected] in which the intensities of several specific ion beams are recorded rather than the entire @[email protected] An alternative recommended term is multiple ion (peak) @[email protected] The use of the terms multiple ion detection and mass fragmentography are not recommended, because in the case of the former, it is the @[email protected] of several peaks which should be emphasized rather than the detection of different ions, and in the case of the latter it is often not fragments that are being monitored but peaks from molecular ions.
