Sometimes the integration result is not ideal for all injections. This article outlines the step-by-step instruction to manually integrate peaks.
There are 2 ways to integrate peaks in OpenLab CDS:
With the Manual Integration tools in Data Analysis, you do not need any toolbar buttons to choose the right tool. The system automatically selects the appropriate tool when you move the mouse pointer over the chromatogram. Visual feedback is continuously given to indicate what tool is active and what part of the data will be modified by the currently active tool.
Figure 1 shows an example of the Intelligent Cursor in action. A meaningful command hint (Split Peaks in this case) and a specific cursor indicate the active tool. The affected peaks are highlighted.
Many of the Manual Integration tools interact with Attractors . They are usually visible on the signal and at baseline points of the adjacent elements. When the Cursor approaches an Attractor, it will automatically snap to the Attractor. This allows you to position new elements directly on the signal or directly attached to adjacent baseline segments (see Figure 2)
Steps to Follow
Caution: Manually integrated peaks are deleted if you click - Reprocess All - Clear corrections.
