Integration Method

The options in the Integration Method dialog box allow you to view or alter the
integration method. After you change any of the integration parameters, the
chromatogram will automatically be re-integrated so you can see the effect of the
new integration values. The Integration Method is used to determine the compound
peaks and calculate the peak area. All of these parameters are set as part of the
method. Refer to Integration Method on page

175 and the assay notes before

making changes to the integration method.

When

Automatic Integration

is enabled the software automatically selects the

Slope Up and Slope Down values and minimum height based on a sampling of the
signal at the start of a run. Ensure

Automatic Integration

is selected.
