Winner803 photon correlation nano particle size analyzer Introduction
The photon correlation nanometer particle size analyzer Winner803 is an upgrade of Winner802. It is equipped with a dual-wavelength laser, which can effectively detect certain samples that have absorbance properties and cannot be detected by traditional single-wavelength lasers. Winner803 focuses on the particle size distribution of colored particles, like pigment , Dyes, etc. The instrument uses the principle of dynamic light scattering and photon correlation spectroscopy. The principle is: because the particles do Brownian motion in suspension, the light intensity pulsates with time. The pulse signal is processed by digital correlator technology to obtain the diffusion information of particle motion , Using the Stokes-Einstein equation to calculate the particle size and its distribution.
Mainly applicable to:
Cells, bacteria, medicines, foods, additives, chemical products, emulsions, medicines, fuels, lubricants, paints, dyes, catalysts, calcium carbonate, ink, photosensitive materials, graphite, metal and non-metal powders, abrasives, dust, coal powder , Particle size distribution of sediment, kaolin, coal water slurry and other nano-scale colored particles. Features
1. High accuracy
Using the principle of dynamic light scattering, the use of HAMAMATSU photomultiplier tubes with high sensitivity and strong signal-to-noise ratio and the independently developed CR256 digital correlator can complete the collection and collection of dynamic scattered light in real time without destroying or disturbing the nanoparticle system Function calculation can effectively calculate the particle size and ensure the accuracy of the test results.
2. Strong stability
The optical path system built with optical fiber technology not only makes the photon correlation spectrum detection system small in size, but also has strong anti-interference, ensuring the stability of the test results.
3. Reliable temperature control system
The semiconductor temperature control system is adopted, and the temperature fluctuation is controlled within ± 0.1 ℃, which ensures that the sample is always in a constant temperature state during the test process, avoiding the test deviation caused by the change in liquid viscosity and Brownian movement speed caused by the temperature change, thereby ensuring the test result Reliability.
4. Dual wavelength laser, intelligent automatic switching
The dual-wavelength (λ = 532 nm λ = 432 nm) laser can be used to switch intelligently, and some samples with light absorption properties that cannot be detected by a single wavelength laser can be effectively detected. Technical parameters
