4 Integration

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.
