Commands:
MS/MS Chromatogram > Marker Views > Fragment Ion Group
A fragment ion group view allows to define a set of fragment ions for detection in a chromatographic data set that reflects All Ion Fragmentation (MSE) data. This analysis is only supported for All Ion Fragmentation data sets with only one static selection window.
All Ion Fragmentation data have the characteristic that chromatograms can be generated from fragment masses since like the intact ion data fragment spectra are acquired continuously without selecting a specific precursor mass. If the All Ion Fragmentation chromatograms use multiple selection windows you have to use a Molecular Marker Group.
A Fragment Ion Group view is generated by clicking the Add View button of a Fragment Ion Group in the data collection list view or by using the command MS/MS Chromatogram > Marker Views > Fragment Ion Group. The MS/MS Chromatogram menu structure is only visible when the active view is based upon a chromatographic data set generated by All Ion Fragmentation (MSE).
Activities:
- Adding or removing fragment ions to / from a group: pressing the
button
- Detecting the fragment ions in a chromatogram: dropping the link icon
onto a chromatogram spectrum. The fragment chromatogram is a correlative chromatogram. Only locations where all fragments are present simultaneously are shown.
