LVE: General Description¶
Purpose¶
Application to Analyze Linear Viscoelastic Data
Data Files¶
The first line of the file should contain the sample parameters separated by semi-colons (
;
). It may contain any number of parameters which will be read and saved as file-parameter in RepTate.Then the data columns should appear, separated by spaces or tabs.
.tts
extension¶
Text files with .tts
extension should be organised as follows:
.tts
files should contain at least the parameter values for the:sample molar mass
Mw
,temperature
T
.
3 columns separated by spaces or tabs containing respectively:
frequency, \(\omega\),
elastic modulus, \(G'\),
loss modulus \(G''\).
Other columns will be ignored. A correct .tts
file looks like:
T=-35;CTg=14.65;dx12=0;isof=true;Mw=13.5;chem=PI;PDI=1.04;
