Product Description

Product Description

Winner802/80 dynamic light scattering nanometer particle size analyzer which based on the dynamic light
scattering principle, and also 1st one which use digital correlator in China. And It's upgrade from
Winner801, which is 1st set of Nanometer particle size analyzer. Based on Brownian motion principle,
smaller particle, faster speed, bigger particle, more slowly. It adopt great performance of Japan
HAMAMATSU photomultiplier and self-developed 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 stokes-Einstein equation. the machine is with characters of fast calculation, high
resolution ration, good accuracy and repeatability, therefore it's widely used in company product lab
research and university use.

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 optical path 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 ±0.1ºC,make samples be in aconstant state throughout the testing process, prevent testing error because temperature change will

change liquid viscosity and Brownian movement speed.
 

7) Output parameters: Real particle size distribution, freely set D10-D100, D[4,3],D[3,2], D[2,1],D[1,0]
and specific surface area
