WinFIT has been
developed by NOVOCONTROL for researchers who wish to analyze
dielectric and impedance spectra.
Advanced curve fitting
techniques are used to ensure accurate and fast determination of material
parameters.
Equivalent Circuit Analysis for
impedance spectra is extended by arbitrary complex functions.
Special evaluations for
dielectric measurements in polymer research are included like Havriliak
Negami functions, Williams Landel Ferry (WLF), master plots and time
domain conversion.
Features
Frequency domain
- Non linear curve fitting in the frequency domain
- Special fit functions like Havriliak Negami, Cole Cole,
Cole Davidson, Debye etc.
- Automatically evaluates a series of spectra for several
temperatures
- Separates relaxation from conductivity contributions
- Automatically creates master plot representations
Temperature domain
- Non linear curve fitting in
the temperature domain including Vogel - Fulcher and Williams Landel
Ferry (WLF) fit functions
- Fits relaxation time and
maximum relaxation frequency
- Creates an Arrhenius activation plot related to activation
energy and glass temperature
Time domain
-
Converts dielectric data by numerical Fourier Transform from
frequency to time domain
- Supports complete dielectric time domain representation
including relaxation time distribution, relaxation function,
step response function, peak answer function, time dependent
dielectric constant and conductivity
Data connection and correction
-
Shifts, deletes and inserts
data points with a single mouse click
-
Connects data curves being
measured in different frequency ranges with different analyzers
