Webinar: Dynamic Vapor Sorption (DVS), Application for Amorphous Content Calculations and in situ Raman studies

Date: 30 April 2020 & 14 May 2020

This webinar highlighted a series of experimental methods of water and organic solvent sorption characterization for determining vapor sorption isotherms of pharmaceutical and food material. Using a novel dynamic flow configuration, this gravimetric experimental system can measure both competitive multicomponent adsorption processes as well as water sorption and glass transition processes. This characterization technique can not only be used across a wide range of materials at different temperatures, but is well suited for adsorption studies using organic vapours at high partial pressures.

This webinar also showed a few examples of case studies such as amorphous content calculation and glass transition Tg RH (the critical relative humidity at the specific glass transition temperature). Moreover, we will focus on the characterization of an in situ study of camera and Raman applications during a DVS experiment.

Presenter:

Dr. Damiano Cattaneo is the Senior Instrumentation Scientist for Surface Measurement Systems. Damiano obtained his PhD in Chemistry (Material Science) at the University of St Andrews (UK) in December 2015. His research project was focused on using porous materials for biomedical applications. Specifically, he investigated the development of porous coordination polymers (MOFs, COFs and Porous Organic Cages) and Zeolites as gas and drug delivery systems for biomedical devices. Dr Cattaneo has a Masters degree in Medicinal Chemistry (Pharmaceutical Chemistry and Technologies) from Università degli Studi di Milano (IT). During the last year of his Masters degree he also worked as a researcher on drug discovery and total synthesis of anti-Parkinson drugs (inhibitor of muscarinic receptors) at the Department of Pharmaceutical Sciences “Pietro Pratesi” (Milan, Italy).

Since joining SMS in 2016, he has worked on the development of advanced in-situ experimental surface science techniques using molecules as probes for studying catalysts, zeolites, MOFs, polymers, pharmaceuticals, composites and cement materials under relevant industrial conditions. Dr Cattaneo has also helped with the development, testing and launch of the new DVS Adventure, Resolution and Endeavour products.
