Review a chromatogram in the Chromatogram Editor
Inspect multiple chromatograms one by one in the Chromatogram Editor
All opened chromatograms (one or multiple) are accessible via the tabs at the top of the Chromatogram Editor (highlighted). In the Chromatogram Editor only one chromatogram can be activated and displayed at the time (pressing the according tab). For overlaying signals (TICs or EICs) separate views are available.
- Zooming: Select desired section (rectangle) with the mouse keeping the left mouse button pressed
- Unzoom: Press right mouse button > Unzoom. Here you have the option to reset to the initial state ("Reset 1:1"), reset only the x-axis or y-axis to the initial state, or to the previously zoomed window ("Previous Selection"), which is helpful when you magnify regions in several steps.
- Move left/right: When you have zoomed into a region you can use the keys or to move left or right
- Adjust y-axis range: use the keys or to reduce or enlarge the y-axis range
- Adjust x-axis range: use the scroll wheel to reduce and enlarge the x-axis range
- Select a scan to inspect a mass spectrum: double-click left mouse button at the according retention time. How to review the mass spectrum at the selected scan is described here.
- Inspect/compare adjacent mass spectra scan by scan: press and hold the key and use or to move left or right. For this to work a scan has to be previously selected (double-click left mouse button).
- Set a defined retention time window for review: the „Info“ tab at the bottom of the editor window allows to select an exact start and end retention time for display. After entering the desired values press „Set Retention Time Range“ and go back to the „Chromatogram“ tab.
- Select a peak to inspect a peak mass spectrum: press and hold here. Note, that this action is only possible if peaks have been previously detected. Detected peaks are marked by a small triangle at the peak maximum. See here how to detect peaks. Alternatively, peaks can be selected via the peak list. , move the mouse cursor onto the peak to review and double-click the left mouse button. How to review the mass spectrum of a peak is described
