单词 | selected ion monitoring |
释义 | selected ion monitoringselected 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. |
