selected ion monitoring(redirected from multiple ion monitoring)
selected ion monitoringA term defined in the context of mass spectrometry as the practice of monitoring and recording ion currents at one or more selected ion m/z values with time, rather than recording full mass spectra, as sample is introduced into the ion source. Because the detector is integrating signal for a longer time at the relevant ion, limits of detection can be lowered, at a cost of increased susceptibility of the analysis to unexpected interferences.
