Subject: [spectroscopy] Peak Fitting Software

PeakFit 4.12 helps you separate overlapping peaks by statistically
fitting numerous peak functions to one data set, which can help you
find even the most obscure patterns in your data. The background can
be fit as a separate polynomial, exponential, logarithmic, hyperbolic
or power model. This fitted baseline is then subtracted before peak
characterization data (such as areas) is calculated, which gives much
more accurate results. And any noise (like you get with
electrophoretic gels or Raman spectra) that might bias raw data
calculations is filtered simply by the nonlinear curve fitting
process. Nonlinear curve fitting is essential for accurate peak
analysis and accurate research.
