Surface area is an important physical property that influences the reactivity, dissolution, catalysis, and separation of materials. The surface area often must be carefully engineered and measured to optimize specific functions. In this webinar, our applications lab will help explain BET theory, the theory behind surface area as well as how to ensure good BET measurements.

Modern Particle Characterization Technique Series VI: Zeta Potential
Dr. David Fairhurst | Colloid Consultants, Ltd

Suspensions are two-phase systems implying that an interface exists between the surface of the material and the liquid in which it is dispersed. The bulk properties of any suspension are dependent upon – and controlled by - two fundamental parameters: the extent of the particle-liquid interface which is characterized by, for example, particle size; and the nature of that interface, characterized by, for example, surface charge.
The influence of changes in the two parameters permeates every aspect of suspension formulation, testing and manufacture and need to be monitored in order to predict and control suspension behavior. Since surface charge directly affects material performance and processability, measuring zeta potential is a convenient and reliable indicator of its magnitude.
This webinar will explore the importance of using such measurements and its utility in characterizing a variety of industrial materials.

Best Practices for Multiparticulate Formulations: The Importance of Computational Design and Process Analytical Technology

Multiparticulate (MP) dosage forms provide opportunities to modulate drug release characteristics and target specific release sites within the GI tract. Fluid bed bottom-spray (Wurster) coating is routinely used to apply successive coating layers in the development and manufacture of these multiparticulate formulations.
During development a key consideration is the amount of coating applied to achieve a target release profile. Typically, the quantity of coating is determined by the application of increasing percent weight gain until the desired release is obtained. While this approach has been successful, it’s time-consuming and lacks a strategy to achieve process control and long-term commercial success.
Experts in multiparticulate applications from Colorcon and Innopharma Technology will discuss how computational design and PAT can help build more robust formulations, predict multiparticulate performance, and accelerate development by reducing traditional iterative trial and testing practices in development.
Discover how the best practices and technology presented here will accelerate formulation development and improve quality outcomes for your multiparticulate formulations.
