Product Description
DLS-802 Dynamic Light Scattering Particle Analyzer Profile
DLS-802 nanometer particle size analyzer is based on the Dynamic Light Scattering principle, the first manufacturer used digital correlator in China. It was upgraded from DLS-801 which is the first set of nanometer particle size analyzer in China.
Based on Brownian motion principle, the small particles cause the intensity to fluctuate more rapidly than the large ones. It adopts 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 angles, 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 factory production labs, researching institutes and universities.
DLS-802 Dynamic Light Scattering Particle Analyzer 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 are 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, ensure good accuracy.
4. High speed data collection and calculation
Self-developed patent product-CR256 digital correlation, it can finish dynamic scattering light intensity collection and autocorrelative function by 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-fiber technology, with 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.
