Winner 802 Dynamic Light Scattering Nanoparticle Size Analyzer
Winner802 is latest nanometer particle size analyzer, upgrade from Winner801 which is 1st nanoparticle size analyzer in China, from software to hardware,originally manufactured by Winner Particle Instrument stock Co., Ltd., based on the dynamic light scattering principle, and also 1st one which use digital correlator in China, Based on Brownian movement principle, smaller particle, faster speed, bigger particle, more slowly.It adopt great performance of HAMAMATSU photomultiplier and selfdeveloped high speed digital correlator as core parts, Get diffusion coefficient by test scattering light change in some angle, and calculate particle diameter and distribution according to StokesEinstein equation.therefore, it's the most matured instrument with good accuracy and repeatability in China. Winner802 can test wide distribution samples size range from 1 to 10000 nanometer,which has the characteristics of easy operation, high precision and wide test range, fast test speed and stable test data etc. It applies to the fields of production, scientific research and teaching of nanometer materials(powders, suspension and emulsion),
Winner, formerly known as the Institute of Jinan University, have built good partnership with the universities since 1985, and for now, 80% of China university choose winner802 as research instrument because of good performance at cost price.

Main Features:
1) Advanced test principle:
Dynamic light scattering principle and photon correlation spectrum technology, according to Brownian motion speed of particle to
test particle size, different size of particles have different speed, when laser illuminate these particles, it will make scattering light
happen different speed of fluctuations- downs.Photo correlation spectrum method will analyze these particle size according to
Photon fluctuations -downs in particular direction.
2) High resolution:
Using PCR technology test nanometer-scale particle size, must be able to distinguish nanosecond signal fluctuations. The core
components of the instrument is CR256 digital correlator developed by our company, with 8ns high resolution speed.
3) High sensitivity and Noise-signal ratio
Detector is composed of imported HAMAMATSU photomultiplier, so ensure good accuracy.
4) High speed data collection and calculation
Self-developed patent product-CR256 digital correlation, It could finish dynamic scattering light intensity collection and autocorrelative
function real time calculation, Data processing speed is up to 162M, effectively reflect dynamic scattering light information of different
sizes of particles.
5)High stable light system
Photon correlation spectrum detect system adopt optical-fibre technology, smaller size and high anti-interference and reliability.
6)High precision constant temperature control system
Semiconductor temperature control technology, precision control within ±0.2℃，make samples be in a constant state throughout the testing process, prevent testing error because temperature change will change
liquid viscosity and Brownian movement speed.
7) Output parameters: particle size distribution(D100,D97,D50,D10,S/V, etc.)
