12. If the compound peak is the only peak within the retention time window, click
Update
or double-click on the peak to open the Update dialog. If the
information in the box is not correct, enter the correct data and click

.
OR
If the compound peak is not within the retention time window or if there are
other peaks in the retention time window, drag the center, blue, dashed line to
the desired peak and the retention time will be updated automatically.
13. Repeat this procedure for each library compound.
14. Select
Re-integrate
from the Analyzer menu.
Each compound should be correctly identified.
15. If you are using another column for your application, repeat this procedure for
the next column.
16. Save the assay and then send it to
Explorer.
17. Using SiteChart, switch to the
Instrument
tab and run an analysis on each
column.
18. Ensure all compounds are correctly identified and then use these analyses to
calibrate
Explorer.
Updating the Calibration Curve
After you have updated the compound retention times you can also update the
calibration curve for each library compound. It is not necessary to update the
calibration curves, but multiple point calibration will provide the most accurate
response.
1. In the SiteChart software, select the
Assay
tab.
2. Select the column/detector combination required for your compound.
Ensure your compound is already listed in the library.
