His talk will take you through classical and contemporary applications of these techniques, showcasing their reciprocal insights. Through this series of case studies, you’ll learn how zeta potential is used today in industry and get a sense of the interplay of solid- and solution-state measurement techniques. ## This Webinar will Cover: - Case studies showcasing the utility of [zeta potential](https://covalent.com/techniques/morphology-structural-analysis/zeta-potential/) measurement in industries including Biotechnology, Biopharmaceuticals, and Semiconductors and more. - When and why solid-state and solution-state zeta potential measurements are measured. - Why these two techniques work best together. ## The Yin-and-Yang of Zeta Potential Analysis You may recognize the term “zeta potential” as a descriptive property for particles in solution. In such colloidal systems, this parameter is paramount for predicting interactions, forecasting stability or aggregation, controlling thin film formation, and optimizing formulations. Yet there is an implicit synergy often overlooked in zeta potential analysis. Colloidal particles – in suspensions, emulsions, electrolytic solutions, and more – are rarely interesting on their own. To get a complete picture of these systems, one must probe the dispersed particles and the solid surfaces they interact with. The applications discussed in this webinar highlight the value of solid- and solution-state zeta potential measurements and exemplify this synergy. Save your spot in the live event to learn how both techniques drive innovation in major industries today.
