Particle Size, Zeta Potential, and Stability - Three Connected and Essential Insights

Particle size, zeta potential, and stability are often treated separately, but they form an interconnected system that defines dispersion behavior. Particle size reveals structure, zeta potential uncovers interparticle interactions, and stability shows how both translate into real-world behavior over time. These parameters continuously influence each other: changes in surface charge can drive aggregation and shift particle size, while size variations impact interactions and stability.

Individually, each parameter provides critical insight. Together, they deliver a complete understanding of colloidal behavior. Relying on isolated measurements or empirical stability tests alone limits understanding and slows development. This integrated approach transforms formulation from empirical adjustment into predictive science.

Microtrac uniquely delivers this full picture by measuring particle size, zeta potential, and stability without dilution, preserving real conditions while saving time and enabling faster decisions and more confident formulation outcomes.
