Product Description

Winner802 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 nano meter-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 ±0.1℃，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: Real particle size distribution, freely set D10-D100, D[4,3],D[3,2], D[2,1],D[1,0] and specific surface area.

FAQ

Purchase laser particle size analyzer need know points:

(1) What materials need test?
If suspension/emulsion, must choose liquid dispersion particle size analyzer, and some materials are also reacted with water, so need liquid dispersion particle size analyzer also. Generally, cement, metal powders and pharamcy materials need dry dispersion model particle size analzyer.

(2) What size range need test?
By now, Based on MIE scattering, laser particle size analyzer can test the particle range is 0.01um-2000um.
If materials range is not so wide, for example, 10um-20um, smaller range of particle size distributon choose closer range model will be preciser, no need to buy large range model.
 

(3) What is dispersion media?
For liquid model, in order that sample can disperse well and circualte in the laser particle size analyzer, generally we need use water, alochol or organic solvent as dispersion media.For dry dispersion model, just use compressed air as dispersion media.In the current market, Dry laser particle size analyzer cost is higher than liquid dispersion models, so if can test well, liquid model is better.
