Commands:
View > Ion Group
View > Unlink Ion Group
View > Charge State Determination
Sequences > m/z Chromatogram
Arcadiate > Preferences... > Quantification
An ion group lists chromatographic ions defined by their m/z value and retention time. They are used to quantify targeted ions.
An Ion Group view can be generated by clicking the Add View button in the list view of a data collection or by using the command View > Ion Group. An ion group is used to determine ion volumes of specific chromatographic ions.
Activities:
- Determination of the ion volumes in a specific chromatogram: dropping the link icon
onto a chromatogram view
- Displaying the quantitative chromatogram, a chromatogram of a centroided, noise reduced ion: clicking onto the blue colored ion volume number of an ion
- Editing the ion volume number: displaying its chromatogram and changing its selection by ⌘ click-dragging over the chromatogram (only when the ion volume was determined by integration - see Arcadiate > Preferences... > Quantification: by integration).
- Re-establishing the default ion volume figure: clicking on a blue colored ion volume figure of the ion
- Unlinking the ion group from a chromatogram: command View > Unlink Ion Group
- Determining the ion volumes in several chromatograms: dropping the link icon
onto a chromatogram group whose chromatograms are aligned. The ion group has to be linked with a chromatogram that is part of the group to define the retention times of the ions in the other chromatograms.
- Charge state determination of ions in a chromatogram: the command View > Charge State Determination if the ion group is associated with a chromatogram
- Display the m/z chromatogram of a selected ion: Sequences > m/z Chromatogram
