YK-N9 It uses a high-speed photon correlator and a professional high-performance photomultiplier tube as the core device. It has the characteristics of fast, high resolution, repeatability and accuracy. It is the first choice for the determination of nanoparticle particle size.

Advanced testing principle: This YK-N9 Light-related Nano-particle Size Meter adopts the principle of dynamic light scattering and photon correlation spectroscopy technology to measure the particle size according to the velocity of Brownian motion of particles in the liquid. The Brownian motion of small particles is fast, and the Brownian motion of large particles is slow. When the laser irradiates these particles, the particles of different sizes will cause the scattered light to fluctuate at different speeds. Photon correlation spectroscopy analyzes the particle size based on the fluctuation of photons in a specific direction. Therefore, this instrument has the characteristics of advanced principle and high precision, thus ensuring the authenticity and validity of the test results; it is the first choice for the determination of nano-stimulated particle size.

High sensitivity and signal-to-noise ratio: The detector of this instrument uses a professional-grade high-performance photomultiplier tube (PMT), which has extremely high sensitivity and signal-to-noise ratio for photon signals, thus ensuring the accuracy of the test results;

Extremely high resolving power and super computing function: When using PCS technology to determine the size of nano-scale particles, it must be able to distinguish nanosecond-level signal fluctuations. The core component of this instrument adopts a high-speed photon correlator developed by an application-specific integrated circuit ASIC, which has a very high resolution capability of identifying 6 ns and a very high signal processing speed, and can collect photon numbers and calculate related operations quickly and in real time. Base.

Stable optical path system: The optical path system built by short-wavelength LD pump laser light source and optical 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 as high as±0.1°C, so that the tested sample and the laser light source are in a constant temperature state during the entire test process, avoiding the influence of temperature changes on non-test results, ensuring Tests are accurate and repeatable;

Super-functional analysis software: The inversion algorithm in the analysis software adopts the accumulative method recommended by international standards and the current relatively common non-negative least square method (NNLS) and Contin and other algorithms, and its test results are comparable to similar international authoritative products have good consistency;

Accurate and stable testing: The perfect combination of high-performance hardware and internationally standardized inversion algorithms has created the accuracy and repeatability of Nano90 test results, and its test accuracy and repeatability are higher than international standards.
