e-SPRESSO WEBINAR: Particle Characterization Makes the Best Medicine
Pharmaceutical solids rely on certain physical characteristics to be fully functional. These include surface area, porosity and pore size, and density. Surface area controls dissolution rate, for example, density reflects volume filling behavior, and pore size and volume affect fluid permeability and crush strength. Control of raw materials and processes requires a detailed evaluation before during and after manufacturing to ensure high quality and predictable behavior.
· Surface area of powders and dissolution
· Density by gas pycnometry and powder tapping
· Measuring porosity
In this webinar, you will learn how gas adsorption is used to determine the interface between a solid and a surrounding liquid, how density measurements of powders and solids are made quickly and accurately, and how forcing mercury into pores under pressure reveals both pore size and pore volume.
Dr Martin A. Thomas has more than forty years of industrial experience in the characterization of powders and porous materials. After studying for his Master’s degree in analytical chemistry and then his Doctorate in inorganic/physical chemistry - both at the School of Chemistry, University of Birmingham (UK) - he joined Cookson Group's Central Research labs where he began his specialization in powders and porous materials. He joined ICI's Catalyst Research Centre (now a Johnson-Matthey facility) in 1985 and spent six years as a Principal Research Officer in charge of porous materials characterization.
In 1991 Dr. Thomas joined Quantachrome Instruments which became part of Anton Paar in 2018. He is currently serving as Lead Scientist for the Surface and Pores product line at Anton Paar.
Dr. Martin Thomas has authored several research articles and books and has also been co-author of ten patents relating to porous materials and their characterization.
