Copying of chromatogram using Mathematical Operations

Following chapter describes how to copy a modified chromatogram into a new one without changing the original chromatogram. For example we set up new Offset of Y-axis and this modification is about to saved in new chromatogram and want to keeping the original chromatogram unchanged.

  1. Open your chromatogram that you want to work with.
  2. In Chromatogram window click Display - Properties to open Graph Properties and go to Signals tab.
  3. Into Field Y Offset write down value of desired offset in mV, in this example we choose 333 mV, and click OK button.

  1. Select Chromatogram - Overlay - Mathematics... and the Mathematical Operations window will open.
  2. Select Copy option . Check Save as Chromatogram , name the new chromatogram and click the OK button.

  1. Both chromatograms will be displayed in overlay mode.
  2. Restore the original chromatogram by navigating to Graph Properties - Signals as in step 2.
  3. Select the original chromatogram , click Original button and close the dialog by clicking OK.

  1. Both chromatograms will be displayed in overlay mode as shown in the next image.
