Learn about Chemometrics methods

applied to Process Analytical Technology (PAT)

In-house sessions

SIMCA® or PLS_Toolbox®

3 days

Researchers, scientists and engineers


This training session in multivariate data analysis, applied to PAT (Process Analytical Technology), is intended for people wishing to:

  • Learn the basics of multivariate data analysis, also called Chemometrics, as part of the PAT initiative
  • Set up data analytics tools for PAT processes
  • Know the performances and limits of the sensors used for rapid control of products and processes


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 can be held on different chemometrics software: SIMCA® (Umetrics Sartorius), PLS_Toolbox® (Eigenvector Research Inc.) …
