[ sedfit ]
For a relatively recent video tutorial on c(s), see https://sedfitsedphat.nibib.nih.gov/tools/Tutorials/Forms/AllItems.aspx
Because the use of Sedfit requires some theoretical background on sedimentation analysis, there are websites with introductions in
* Lamm equation solutions
* systematic noise analysis
* size-distribution analysis
* van Holde-Weischet analysis
* Compressibility of water and organic solvents
* Sedimentation in dynamic self-forming density gradients
* generating simulated data
There is also a step-by-step tutorial on how to use Sedfit.
You can also consult the step-by-step protocol https://www.nature.com/articles/nprot.2017.064 (this is using fluorescence optical data, but the data analysis applies equally to other optical systems).
As documentation please refer to the following books, which have specific information on SEDFIT and SEDPHAT functions as side-bars nested into the description of theory and experiment of analytical ultracentrifugation (AUC):
Note also the Experimental Protocols website for how to plan, conduct, and plan analysis of AUC experiments.
