Implementing Chemometrics in PAT

Course Description

Some of the most profitable uses of chemometrics technologies to date have been in the development, deployment and support of multivariate Process Analytical Technologies (PAT). However, this application area involves some unique considerations, including regulatory compliance, on-line model deployment logistics, and model performance monitoring. Implementing Chemometrics in PAT is designed to familiarize the student with the various chemometrics tool and other associated tools that are needed for effective PAT applications. Deployment software demonstrations and PAT case studies will be used to help illustrate the course material. The course includes hands-on computer time for participants to work example problems using PLS_Toolbox and MATLAB.

Prerequisites

Chemometrics I–PCA and Chemometrics II–Regression and PLS or equivalent experience.
