Participants in a workshop at the AAPS Annual Conference and Exposition were given insights on the topic of 'Powder Flow and Process Analytical Technology - Tools for Implementation of QbD'.
Christina Pattoni from Pfizer spoke about her team's use of the Freeman Technology FT4 Powder Rheometer.
Stephen Closs from Patheon shared his experiences of using the C-Therm ESP Thermal Effusivity instrument.
Stephen Wu of Covidien talked about both technologies in respect of work with pharmaceutical lubricants.
Each presentation prompted lively debate, highlighting the many challenges people share when it comes to successfully processing powders.
Tim Freeman, director of operations for Freeman Technology, and Rob Pugh, ESP product manager at C-Therm, planned the event to be valuable for anyone seeking greater understanding of different formulation and PAT tools to facilitate QbD.
As well as the contributions of the invited speakers, presentations on the basics of thermal effusivity and on powder characterisation provided additional background information on the analytical technologies themselves.
