Zeta Potential Analysis Service
Dynamic Light Scattering (DLS) for Zeta Potential Measurement
Zeta potential refers to the surface charge of particles in a fluid and plays a crucial role in material stability. Dynamic Light Scattering (DLS) is a highly reliable method for determining zeta potential. This technique relies on the Brownian motion of particles and utilizes visible light radiation with a wavelength of 633 nm. The method can measure the zeta potential of colloidal samples, suspensions, and emulsions.
Key Features of our DLS Device
Our Zetasizer Nano ZSP System is equipped with a 633 nm laser and utilizes capillary-type cuvettes made of polystyrene with gold electrodes, which are disposable for convenience. It enables precise measurement of zeta potential for particles ranging in size from 3.8 nm to 100 micrometers.
