Dynamic light scattering nanoparticle tracking laser dls scattering particle size distribution analyzer
CY-N9 is our latest nanometer particle size analyzer based on dynamic light scattering principle. It uses high-speed photon correlator and professional high-performance photomultiplier tube as the core device, featuring fast, high resolution, repeatability and accuracy. It is the first
choice for nanoparticle particle size measurement.
Main performance characteristics:
Advanced Test Principle: This instrument uses the dynamic light scattering principle
and photon correlation spectroscopy techniques to determine the particle size based on the
velocity of the Brownian motion of the particles in the liquid. The small particle Brownian
movement speed is fast, the large particle Brownian movement speed is slow, the laser illuminates these particles, and the particles of different sizes will make the scattered light appear different
speed fluctuations. Photon correlation spectroscopy analyzes the particle size based on photon fluctuations in a particular direction. Therefore, the instrument has the characteristics of advanced principle and high precision, thus ensuring the authenticity and effectiveness of the test results; it
is the first choice for the determination of nano-activated particle size.
High sensitivity and signal-to-noise ratio: The detector of this instrument adopts professional-grade high-performance photomultiplier tube (PMT), which has extremely high sensitivity and signal-to-noise ratio to photon signals, thus ensuring the accuracy of test results.
Extremely high resolution and superior computational power: Using PCS technology to measure nanoscale particle size, it must be able to resolve nanosecond signal fluctuations. The core component of the instrument uses a high-speed photon correlator developed by an application-specific integrated circuit ASIC. It has a very high resolution capability of 6ns and a very high signal processing speed. It can quickly collect real-time photons and calculate related operations. basis.
Stable optical path system: The optical path system constructed by short-wavelength LD
pumped laser source and fiber technology makes the photon correlation spectrum detection system not only small in size, but also has strong anti-interference ability, thus ensuring the stability of the test.
High-precision temperature control system: The accuracy of the sample cell
temperature control system and the laser temperature control system is up to ±0.1 .C, so that the sample to be tested and the laser source are in a constant temperature state throughout the test process, avoiding the influence of temperature changes on the non-test results, ensuring Testing is accurate and repeatable;
Ultra-functional analysis software: The inversion algorithm in the analysis software adopts the accumulative method recommended by international standards and the current common non-negative least squares (NNLS) and Contin and other algorithms. The test results are similar to
those of international authoritative products. Has good consistency;
Accurate and stable testing: The combination of high-performance hardware and
internationally standardized inversion algorithms results in the accuracy and repeatability of Nano90 test results. The test accuracy and repeatability are higher than international standards.
