Chromatogram window

  • The Chromatogram window can be opened also manually by clicking on the Chromatogram icon in the Instrument window.
  • Here you can evaluate your previously acquired data or open our sample chromatogram to get familiar with the basic functions which will be covered in this chapter.
  • Use the File - Open Chromatogram... command or click the open icon and select the Wine_Sample.prm file and press the OK button.
  • The Chromatogram window is divided into two parts: the Graph (upper) pane and the Results (lower) pane.

The Chromatogram window

  • Clicking on a cell in the Result table will highlight the peak (or peaks when selecting multiple cells) corresponding to the row(s) you just selected.
  • Only one detector signal can be active at a time. The active signal can be identified in three ways:
    • in the legend section at the upper right corner of the graph , where the active signal is displayed in bold text
    • in the Overlaytoolbar , where it is marked with a debossed icon
    • by noting the color of the graph outline and table headers.
  • Try to change the active signal by double clicking on its name in the legend section. You will notice that the Result table has changed.
  • To change the color of the active signal click on the desired color in the Overlay toolbar.
  • You can change the integration of peaks using the interactive icons on the toolbar on the left side of the Chromatogram window , selecting the Integration operation in the Chromatogram menu, or directly in the Integration tab . Any changes made either way will change the Integration table and can be copied to the template method.
  • By clicking the View button , you can open the calibration linked to this chromatogram.
  • To display more than one chromatogram you can enable the Overlay mode .

Note:

Already measured chromatograms can be reprocessed in the Batch dialog using the newly created method to apply the adjusted Integration table.
