NEW COURSE

This course will present an overview of the state of the art in ion-exchange process chromatography: development, scale-up and optimization of preparative chromatographic processes. The attendees will learn how to develop ion-exchange preparative chromatographic processes. They will gain knowledge on the scale-up and optimization of ion-exchange processes.

The course will cover the fundamentals of process chromatography and the tutors will present a rational and proven methodology for the design of efficient and robust chromatographic processes. They will show how this approach serves both the design of new processes and the resolution of issues encountered in the daily life of chromatographers concerned by process development and scale-up. The methodology rests upon the rigorous description of the physical phenomena at stake, which includes thermodynamics, kinetics of mass transfer and hydrodynamics of the separation. Predictive models are derived from the understanding of these phenomena and are then used to assess the impact of operating parameters on the process performances. A focus will be done on ion-exchange chromatography and main features of the thermodynamic model.

Major applications of ion-exchange chromatography will also be presented, spanning across the ton-scale amino-acids or organic acids production, sugar softening, metals separation or the purification of proteins with stringent purity constraints. Various case studies inspired from real industrial examples or taken from the most recent literature will illustrate that the general approach presented during these two day applies as a roadmap, irrespective of the application, and ultimately leads to the development of reliable and robust processes.
