Sorption Science Webinars/Workshops Directory

This educational webinar explores the use of surface energy measurements as related to granulation performance.  In particular, this session focuses on the well-established vapor sorption technique of Inverse Gas Chromatography (IGC).  This session discusses several case studies on how surface energy measurements can be used to help formulate and characterize both wet and dry systems.  In addition to granulation case studies, other unit common powder operations, such as milling, will be presented and related to surface properties.

Webinar title: Particle Engineering in Pharmaceutical Solids Processing: Surface Energy Considerations

Topic: This webinar presented by Dr Daryl Williams from Imperial College London reviews the surface energy and surface energy heterogeneity of crystalline solids, methods for the measurement of surface energy, effects of milling on powder surface energy, adhesion and cohesion on powder mixtures, crystal habits and surface energy, surface energy and powder granulation processes.

This webinar covers an in-depth introduction to the Inverse Gas Chromatography – Surface Energy Analyser (iGC-SEA) technique and the concept of surface energy. It explores the versatility of the iGC-SEA technique and how it can be used in the study of pharmaceuticals, polymers, carbon materials and fibres. The case studies presented highlight the use of the system to measure BET specific surface area, surface energy and surface heterogeneity. Studies also demonstrate the effects of changing conditions of temperature and humidity on materials.
