Results interpretation (fit optimization, and data evaluation and treatment)

Data exportation and setup and recomputation

Hands on with Common Samples such as :

  • Diluted and concentrated samples
  • Broad size distribution samples
  • Very small sample sizes (< 10nm)
  • Proteins approach
  • Emulsions
  • Powders approach
