Practical Insights for Electrophoretic Light Scattering (ELS), Zeta Potential, and Size Analysis

Overview

Characterizing particle size and surface charge, including zeta potential, is essential for applications in biopharmaceuticals and nanoparticle research. This webinar introduces the fundamentals of Electrophoretic Light Scattering (ELS), focusing on measuring charge properties and particle stability. Through case studies, we will explore how ELS and complementary light scattering techniques support formulation development, aggregation screening, and stability assessments. Discussions will cover common challenges in zeta potential measurements and strategies for ensuring reliable data. Additionally, we will highlight recent advancements in ELS instrumentation that enable scientists to automate measurements and obtain high-quality results with greater efficiency reproducibility.

Key Learning Objectives:

§  Analytical Techniques: Gain knowledge on advanced light scattering for characterizing charge and zeta potential

§  Case Studies: Explore real-world applications of light scattering techniques in assessing the quality and stability of LNPs and antibodies
