Abstract (en)
[origin: EP1598850A2] The invention relates to a mass spectrometer, in particular a time-of-flight mass spectrometer, with fragmentation of pre-selected molecule ions for the acquisition of daughter ion spectra. The invention consists in an instrument with devices for generating multiply charged ions of the molecule of interest, for selecting a multiply charged ion species by a mass filter, for fragmenting the selected ions by allowing them to react with low energy electrons in an RF ion guide system, and for analyzing the fragment ions in a mass analyzer.
