WinFIT Impedance
Analysis Software
WinFIT focuses on the analysis ofimpedance and dielectric spec­tra. It reads binary data createdby our WinDETA/WinIMP pro­grams as well as text files in va­
rious selectable formats.
Advanced non­linear curve fit­ting techniques ensure both ac­
curate and fast determination of
key materials parameters.
Equivalent Circuit Analysis of im­pedance spectra is extended byarbitrary complex functions.
The evaluation of dielectric
spectra in polymer research
Is particularly supported by theHavriliak­Negami and Williams­
Equivalent circuit analysis supports definition of arbitrary RLC
Landel­Ferry (WLF) functions.

spectra, their representation inmaster plots and their convers­
ion into the time domain.

Frequency domain

Features• non­linear curve fitting in the frequency domain• special fit functions like Havriliak­Negami, Cole­Cole, Cole­Davidson, Debye etc.
• automatic evaluation of a series of spectra taken, e.g., at various
temperatures• separation of relaxation and conductivity contributions• automatic creation of master plot representations

Temperature domain• non­linear curve fitting in the temperature domain, including Vogel­
Fulcher and Williams Landel Ferry (WLF) fit functions• relaxation time and maximum relaxation frequency fitting• easy creation of Arrhenius activation plots• determination of activation energies and glass temperatures

Time domain• conversion of dielectric spectra to the time domain by numerical
Fourier Transform• complete dielectric time domain representation including
relaxation time distribution, relaxation function, step responsefunction, peak answer function, time dependent dielectric constantand conductivity

Data connection and correction• easy data manipulation (shift, delete and insert) using simple mouse
operations• easy merging of data sets obtained in different frequency ranges
using diverse analyzers

Applications
Impedance analysis anddielectric spectroscopy
are prominent characteri­zation tools for ceramics,
polymers, glasses, liquid
crystals, semiconductors,
batteries, fuel cells, corrosi­
on analysis, biomedicaland biological systems.
Various key aspects of ma­
terials properties such as
molecular relaxations,conductivity, phase sepa­
ration, purity, ageing, cu­ring and many others are
all accessible using thistechnique.
Phase transitions, activati­
on energy, glass tempera­ture, rate of blending, etc.
are evaluated from tem­
perature dependent spec­
tra.
