When a single UV absorbance trace is monitored with a single-wave UV you can
 Autoscale all UV traces to the same scale .
The y-axis scale is based on the signal intensity of the UV trace with the highest
intensity and all other traces are normalized to the intensity of that trace.
 Disable autoscaling .
To autoscale the UV trace
 Do one of the following:
 Click Autoscale on the toolbar to choose a status.
 Right-click the chromatogram, choose Autoscale UV trace, and select
a status.
Annotating the Chromatogram
You can add notes to the chromatogram in manual mode at any time during a run or
after a run completes to associate observations with data points on the
chromatogram. The annotation dialog box contains three fields: Location (in time,
volume, or CV), Title, and Description. When the annotation is saved, its title
appears at the specified location on the x-axis. The description appears in the
run report.
You can add annotations when a method run is in progress. However, if the run ends
while the annotation dialog box is open, the annotation is saved and the dialog box
closes automatically
. When a method run is complete, annotations cannot be added
to the chr
omatogram in System Control. You can annotate completed runs by
opening them in Evaluation mode.
