1、 Basic principles

The nano particle zeta potential analyzer works based on the principles of laser scattering and electrophoresis technology. Laser scattering technology measures the scattering angle and intensity of laser in nanoparticles to obtain the size distribution of nanoparticles. Electrophoretic technology measures the migration speed of nanoparticles under the action of an electric field, and then calculates the surface charge of the particles, namely Zeta potential. Zeta potential is an important parameter for characterizing the surface charge of particles, which reflects the forces of mutual repulsion or attraction between particles, thereby affecting the stability and dispersion of particles in suspension.

2、 Main functions

1. Particle size analysis: The nanoparticle zeta potential analyzer can measure the size distribution of particles, helping users understand the average size and particle size distribution of particles in suspension. This is of great significance for studying the formation, growth, and aggregation processes of particles.

2. Zeta potential measurement: By measuring the Zeta potential of particles, the surface charge properties of particles can be evaluated, thereby determining the stability of particles in suspension. The higher the Zeta potential, the greater the repulsive force between particles, and the more stable the suspension.

3. Surface charge determination: In addition to Zeta potential, the size and properties of the surface charge of particles can also be determined, which is crucial for understanding the interaction between particles and their surrounding environment.
