Products Description

Winner803 dynamic light scattering nanometer particle size analyzer which based on the dynamic light scattering principle. 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. It's widely used in company product lab research and university use, especialy good for testing particle size distribution of coloured particles.

+ Advantages

(1) Dual-wavelength laser, automatic switching

Exclusively using dual-wavelength (A= 450nm, A= 532nm) laser to build the optical system. The correlation spectrum detection system is not only small size, but also has strong anti-interference ability, thus ensuring the stability of the test. For some samples with absorbance properties, which can not be detected by traditional single-wavelength laser, it can be tested effectively.

(2) 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 happendifferent speed of fluctuations-downs.
Photo correlation spectrum method will analyze these particle size according to Photon fluctuations -downs in particular direction.

(3) 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 Winner. Its resolution speed can reach up to 8ns.

(4) High sensitivity and noise-signal ratio

Detector is composed of imported HAMAMATSU photomultiplier, so ensure good accuracy.

(5) High speed data collection and calculation

Self-developed patent product-CR256 digital correlation, it could finish dynamic scattering light intensity collection and auto correlative function real time calculation, Data processing speed is up to 162M, effectively reflect dynamic scattering light information of different sizes of particles.

(6) High stable optical path system

Photon correlation spectrum detect system adopts optical-fibre technology, smaller size and high anti-interference and reliability.

(7) High precision constant temperature control system

Semiconductor temperature control technology, precision control within 0.1°C. It makes samples be in a constant state throughout the testing process, prevent testing error because temperature change will change liquid viscosity and Brownian movement speed.

(8) Precision test report

Output parameters: Real particle size distribution, freely set D10-D100, D[4,3), D[3,2], D[2,11], D[1,0] and specific surface area.
