    JH-N9H Light-related Nanoparto Main performance characteristics:

    Advanced testing principle: The Light-related Nanoparto adopts the principle of dynamic light scattering and photon correlation spectroscopy technology, and measures the particle size according to the Brownian motion speed of particles in the liquid. The Brownian motion speed of small particles is fast, and the Brownian motion speed of large particles is slow. When the laser beam is irradiated on the moving particles, the scattered light at a certain angle (the instrument adopts 90 degrees) changes dynamically with time, and the speed of the change is related to the Brownian motion speed of the particles in the liquid. Photon correlation spectroscopy is used The dynamic scattering spectrum was analyzed statistically and related calculations, and the particle size was calculated according to the Stokes-Einstein equation.

    High sensitivity and signal-to-noise ratio: HAMAMATSU professional-grade high-performance photomultiplier tube (PMT) with low dark count and high sensitivity is used as the detector, which has extremely high sensitivity and signal-to-noise ratio for photon signals, thus ensuring the accuracy of test results High accuracy and high resolution;

    Super computing function: To use 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 the high-speed photon correlator developed by ASIC, which has a very high resolution capability of identifying 6ns and a very high signal processing speed. Base;

    Stable optical path system: The photon correlation spectrum detection system built by the combination of high-power semiconductor laser and optical fiber controlled by constant temperature makes it not only small in size, but also has strong anti-interference ability and stability, ensuring repeatable and stable test results;

    Dual-wavelength laser: Any sample has specific light-absorbing properties, and it is difficult to accurately measure particles that absorb light at this wavelength with a single-wavelength laser. The N9H dual-wavelength laser can perfectly measure all samples, and the dual-wavelength can be switched freely.

    High-precision temperature control system: The accuracy of the sample pool 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 the test results and ensuring the test results accuracy and repeatability;

    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 test: The perfect combination of high-performance hardware and internationally standardized inversion algorithm makes the test results of JH-N9HLight-related Nanoparto accurate and repeatable, and its test accuracy and repeatability are higher than the requirements of international standards.

    This Light-related Nanoparto has reached the test level of foreign nano particle size analyzers!
