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!
Feel free to contact us for a free trial Version!
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.
You can withdraw your agreement at any time for the future via E-Mail to
This DRT implementation is based on ideas and methods introduced by the Ciucci group of the The Hong Kong University of Science and Technology.
