Review Peaks

During peak review, the user may want to view a peak in its entirety—or may want to examine the
baseline to find out how well the software found the start and end points of the peak. Use the
automatic zooming feature to do either.
To help the software find a peak, define the exact start and end points of the peak and
background manually. These changes will apply only to that individual peak unless the global
method is updated.
Tip! To review an individual peak, right-click on a point on the curve and then click
Show Peak. The software shows the Peak Review window with the selected peak.
1. Right-click in the Results Table, click Analyte.
2. Select a sample.
3. Click Tools > Peak Review > Pane.
The peaks appear below the Results Table with only the peaks listed in the Results
Table.
4. Right-click in the pane and then click Options.
5. In the Peak Review Options dialog, in the Appearance section, change Num.
rows to 1 and Num. columns to 2.
6. In the Automatic Zooming section, click Zoom Y axis to: 100% of largest peak to
show the entire peak.
