Peak Separation

Total curve is presented as the sum of individual peaks. Each peak is analyzed individually and the following information is reported:

Peak parameters

Shape type
Position of peak
Amplitude
Half width
Asymmetry
Part of Frazer shape in total shape

Analysis for each peak

Onset: X and Y
Left Inflection: X and Y
Peak : X and Y
Right Inflection : X and Y
Endset: X and Y
Contribution to the total area in Percent

The universal peak shape is used, which is the weighted mixture of Fraser-Suzuki and asymmetric Cauchy. The following peak types are the partial cases of the universal peak shape: Gaussian, Cauchy, Pseudo- Voigt (additive mixture of Gaussian and Cauchy), Fraser-Suzuki (asymmetric Gaussian), Laplace, asymmetric Laplace and asymmetric Cauchy.

UV/VIS spectroscopy
NIR and IR spectroscopy
NMR spectroscopy
X-ray small-angle scattering of polymers (for profile analysis with a Pseudo-Voigt profile, the Gauss component indicates the degree of crystallinity)
