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. Refer to

Integration Method on page

150 for details on the integration method before

adjusting any of the integration parameters.

Update Log Listing and Auto Update Log Listing

If the instrument is connected to the computer and is performing runs, completed
runs will be added to the current directory. If you are reviewing compound or log
data from the current directory, SiteChart will update your listing whenever a run is
added to the directory. This could be a time consuming task if you have a long list of
files. To prevent the list from being updated automatically, you can disable this
feature.

To disable the Auto Update feature:

1. Open the View menu and select

Auto Update Log Listing

.

The check mark will disappear and new runs will be logged to the computer
but will not be added to the listing.
