4 Integration
Peak Recognition
Peak Recognition
The integrator uses several tools to recognize and characterize a peak:
• peak width,
• peak recognition filters,
• bunching,
• peak recognition algorithm,
• peak apex algorithm, and
• non-Gaussian calculations (for example tailing, merged peaks).
Peak Width
During integration, the peak width is calculated from the peak area and
height:
Width = Area/Height
or, if the inflection points are available, from the width between the inflection
points.
