Settings for Zeta potential in water treatment

The Zetasizer uses electrophoretic light scattering to find the charge of particles. This charge can mean the difference between dispersed particles and flocculated sediment. That is why Zeta potential in water treatment is important to get cleaner H2O: we want…READ MORE >

Determining the quality of asphalt emulsions using particle size and zeta potential analysis

What are asphalt emulsions and why are they important? They are liquid asphalt cement emulsified in water. They compose of bitumen, water, and an emulsifying agent or surfactant. Asphalt emulsions are integral to the optimum mechanical properties. Modified asphalt emulsions…READ MORE >

Find the Field Strength in your Zetasizer

How can we obtain the applied field strength? When performing electrophoretic light scattering (ELS) measurements, the sample is exposed to an externally applied electric field, and we observe the extra movement that the particles undergo as a result of the…READ MORE >

Zeta potential in salt solution (or any other ions)

Will the zeta potential of my vesicles vary in different buffers?   The short answer is: Yes, it will. In select cases, the value of the measured zeta potential may remain close to the same. However, that is the exception…READ MORE >
