Integration
In this section you will optimize the integration events for the analysis and save
them to the method.
1) Go into the Data Analysis view.
2) From the View menu, select Preferences.
3) Select the Signal Options tab. Make certain that integrate after load is the
only box checked.
4) Find your data analysis directory in the ChemStation Explorer. Double-click
on the Single Runs to place the files in the Navigation Table. Find the data
file, Low.d, and load all signals. The data file is initially integrated using the
default integration events. Make certain both signals A and B are present.
5) After loading, go to the Integration menu and select Integration Events or
select the Select Integration Task tool, then the Edit/Set Integration Events
Table tool.
6) Select DAD Default for the Events Table and insert the following integration
events:
Tangent Skim Mode: New Exponential
Tail Peak Skim Height Ratio: 3
Front Peak Skim Height Ratio: 6
Skim Valley Ratio: 20
Baseline Correction: Advanced
Peak to Valley Ratio: 500
Slope Sensitivity: 50
Peak Width: Set to the narrowest real chromatographic peak
Area Reject: 0
Height Reject: 1
Shoulders Off
7) Reintergrate the chromatogram using the new events. Either select the
Integration menu then Integrate, or the Integrate tool.
8) Examine the current integration. Change settings appropriately. Remove
undesirable peaks (there should be four main peaks) using either the area
reject or timed events.
