DRT Results

Below you can find the calculated DRT, given by the distribution Gamma as a function of the time constant, tau.

The rhd instruments team hopes, that you found this tool useful for your studies.

In our full RelaxIS software you can perform DRT and many other EIS analysis techniques much more comfortably,
even for large datasets!

Privacy Policy

To keep it brief and simple:

Any raw data you submit to our server while using the RelaxIS DRT application is only used temporarily in volatile memory for the purpose of calculating the results and is then discarded immediately.

No person can manually inspect your data in any way.

Data we do store

The server keeps connection logs containing the following fields

  • Date of the request
  • Anonymised IP address and User Agent (e.g. browser type) of the remote endpoint
  • Type of request, e.g. POST/GET
  • Type of task to be performed by the server (plotting or DRT calculation)

These logs are only used for internal performance monitoring and usage statistics. The data is not shared with any third-parties.

Please also refer to our dedicated privacy policy or feel free to contact us if you have any questions.
