4.7.1Using Baseline Offset

Use the Baseline Offset command to offset the y-axis in a chromatogram to improve the appearance of a trace or correct a sloping baseline.

To use Baseline Offset:

1.Activate the window on which you want to perform the offset.

NOTE: You can select a Chromatogram or Spectrum window. If you do not activate the correct type of window before performing the next step, the software does not select values when you click-drag on the trace. For example, you must select a Chromatogram window before starting baseline offset on a chromatogram.
