To integrate a chromatogram, the integrator ...
defines the initial baseline,
continuously tracks and updates the baseline,
identifies the start time for a peak,
finds the apex of each peak,
identifies the end time for the peak,
constructs a baseline, and
calculates the area, height, peak width, and symmetry for each peak.
This process is controlled by integration events. The most important events are initial slope sensitivity, peak width, shoulders mode, area reject, and height reject. The software allows you to set initial values for these and other events. The initial values take effect at the beginning of the chromatogram.
In most cases, the initial events will give good integration results for the entire chromatogram, but there may be times when you want more control over the progress of an integration.
The software allows you to control how an integration is performed by enabling you to program new integration events at appropriate times in the chromatogram.
