Winner802/803 Photon-related Nanoparticle Size Analyzer

Product Introduction:

Photon-related Nanoparticle Size Analyzer Winner802This product is the outcome of the National Science and Technology Innovation Foundation Project for Small and Medium-sized Enterprises (Project Code: 10C26213704395), and it is one of the first in China to use the principle of dynamic light scattering for nanoparticle size analysis. The instrument employs dynamic light scattering and photon correlation spectroscopy techniques. Due to the Brownian motion of particles in the suspension, the intensity of light fluctuates over time. The pulse signals are processed using micro-nano digital correlation technology to obtain diffusion information about particle motion. Particle size and distribution are then calculated using the Stokes-Einstein equation.

Photon-related Nanoparticle Analyzer Winner803It is an upgraded model of Winner802, equipped with a dual-wavelength laser.For samples with absorbent properties that cannot be detected by conventional single-wavelength laser devices.The Winner803 803nm Laser Particle Sizer is dedicated to effective detection of particle size distribution in colored particles, such as pigments and dyes.

Product Advantages:

High sensitivity and signal-to-noise ratio

Utilizing the principle of dynamic light scattering, with high-sensitivity HAMAMATSU photomultiplier tubes and our self-developed CR256 digital correlator, we can collect dynamic scattered light and perform calculations in real-time without disrupting or interfering with the nanoparticle system. This effectively calculates the particle size distribution, ensuring the accuracy of the test results.

Strong anti-interference capability

Optical path systems built with fiber optics technology ensure that the photon-related spectral detection system is not only compact but also highly resistant to interference, guaranteeing stable test results.

Reliable temperature control system

Utilizing a semiconductor temperature control system, temperature fluctuations are maintained within ±0.1 ℃, ensuring the sample remains in a constant temperature state throughout testing. This prevents deviations in test results due to changes in liquid viscosity and Brownian motion speed caused by temperature variations, thereby guaranteeing the reliability of the test outcomes.

Dual-wavelength laser, intelligent switching(Winner803 Exclusive Features)

Utilizing dual wavelengthsλ = 532 or 639 nm, λ = 405 nmLasers with intelligent switching capabilities for effective detection of samples with absorbent properties that cannot be detected by single-wavelength lasers.
