Calculation of Peak Symmetry
Calculation of Peak Symmetry
The ChemStation does not determine the asymmetry ratio of a peak, usually
done by comparing the peak half-widths at 10% of the peak height, or 5% as
recommended by the FDA.
Peak symmetry is calculated as a pseudomoment by the integrator using the
following moment equations:
If no inflection points are found, or only one inflection point is reported, then
the peak symmetry is calculated as follows:
