This section includes:

4.7.1 Using 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.
2. Select Duplicate Active Trace from the Display menu to
keep the original data displayed after processing.
3. From the Process menu, select Baseline Offset.
The Baseline Offset dialog box (Figure 4-12) is
displayed.
