Come and learn chemometrics methods for multi-block data

In-house sessions


1 day

Researchers, scientists and engineers


This training session on multivariate data analysis is intended for people wishing to:

  • Deepen their knowledge in processing data organized in blocks
  • Be quickly autonomous in multi-block data treatment for exploratory and quantitative analysis
  • Assimilate the key steps of data analysis methodology


During the training, the method principles are introduced by a geometric approach. Emphasis is placed on the practical use of the method and the interpretation of the results.

Application exercises are proposed for each method. The training will be held on Unscrambler® (Camo Analytics).

    Marion Berger de Sanofi témoigne sur sa collaboration avec Ondalys My team attended several trainings led by Ondalys (spectral analysis via Unscrambler, Multi-blocks & Independent Component Analysis (ICA)). Each time, we appreciated the clarity of the presentations, making accessible the complex concepts, the technical capacities and the expertise of the trainers coupled with their benevolence towards the trainees. Each event was a pleasure and a success.
