Introduction: The BeNano Zeta nano particle size potentiometer is a newly developed optical detection system for measuring Zeta potential based on the previous generation Zeta 100 nano particle size potentiometer by Dandong Baxter Instrument Company. The BeNano Zeta system uses an electrophoretic light scattering light path system, using phase analysis light scattering PALS technology to detect particles such as Zeta potential. Electrophoretic light scattering ELS uses the Doppler shift of the scattered light generated by the electrophoretic motion of particles, and obtains the information of the electrophoretic motion speed of the particles by detecting and analyzing the original optical signal. The relationship between the particle electrophoresis speed and Zeta potential established by Henry's equation is finally Obtain the Zeta potential and Zeta potential distribution information of the particles in the current system. Features: 1. High-speed test capability: faster test speed, all results can be subsequently batch edited and processed 2. High-performance solid-state laser light source: high power, excellent stability, long life, low maintenance 3. High-performance imported APD detector: extremely sensitive, can effectively detect extremely dilute samples and samples in the sub-nanometer range 4. Intelligent light source energy adjustment: according to the signal-to-noise ratio, the software intelligently controls the light source energy 5.
