Abstract
Ions fragmented from a known precursor ion of a known compound are received by an ion guide that ejects the ions into an extraction region of a TOF mass analyzer. The ion guide ejects the ions using Zeno pulsing mode and the TOF mass analyzer measures intensities of the ions over time, producing a Zeno group of mass spectra. The ion guide then switches to a normal pulsing mode, producing a normal group of mass spectra. A gain is calculated for Zeno mode in comparison to normal mode as a series of ratios of intensities of one or more ions obtained from the Zeno group to corresponding intensities of the one or more ions obtained from the normal group. The gain is used to calculate a percentage of the theoretical gain and is used along with the theoretical gain to quantitate a compound in an on-demand Zeno pulsing quantitation experiment.
