Clarity - Getting Started First “Analysis”

to suggest the initial values based on the

narrowest peak of interest (peak width) and

baseline part with no peaks of interest

(threshold).

Proceed

• Switch to the Integration tab in the Chromatogram

window to see the amendments to the

chromatogram method integration table.

• Use the Global Peak Width and Global

Threshold interactive commands to optimize

the integration of peaks.

• Limit the integration only to areas where peaks

of interest are present using the Integration

Interval command

Note: This will simplify the baseline detection around the

dead volume dips or baseline shifts.

The other integration tools can be used to get

the desired integration, when it is not possible

to do so by the previous parameters (see next

chapter).

5.5.3 Chromatogram modifications

If you wish to edit the automatically generated

baseline, you can manually modify the

chromatogram whenever you like by:

• either interactively

using icons from the tool-

bars located on the left edge of the

Chromatogram

window (or corresponding commands from the

submenu Chromatogram - Baseline, Peak

and Integrations). Modifications are saved in

the Integration table on the

Integration tab.

• or explicitly enter and change parameters di-

rectly in the Integration table on the

Integration

tab.

TIP: The Integration sheet in the Chromatogram window is

used for modifying the current chromatogram. The

Integration sheet in the Method Setup dialog is used

for editing the whole method for newly measured

chromatograms.
