Working Principle

The analyzer uses dynamic light scattering technology to irradiate nanoparticles dispersed in liquid with laser light, analyze the intensity change of scattered light due to Brownian motion, and then calculate the particle size distribution. zeta potential measurement is based on the principle of electrophoretic light scattering, which is based on the electrophoretic light scattering principle, whereby the particles move electrophoretically under the effect of electric field, and then the laser irradiation generates a Doppler shift, and then analyze the shift amount to obtain the particle size distribution through photon correlation spectroscopy technology. The zeta potential of the particles can be obtained by analyzing the frequency shift. The core data acquisition relies on a high-speed digital correlator to ensure accurate processing of electrophoresis and light scattering signals. The precise temperature control system ensures constant temperature throughout the test process, eliminating external influences and improving data stability.
