1.Advanced testing principle: The instrument adopts dynamic light scattering principle and photon correlation spectroscopy technology. The particle size is determined according to the Brownian motion speed of particles in liquid. The Brownian motion speed of small particles is fast, and that of large particles is slow. When a laser beam is irradiated on a moving particle, the
scattered light from a certain angle (the instrument uses 90 degrees) changes dynamically with time. The speed of the change is related to the Brownian motion speed of the particle in the liquid. The dynamic scattering spectra are analyzed by photon correlation spectroscopy, and the relevant calculation is carried out according to Stokes-Einst. Ein equation was used to calculate the particle size.
2.High Sensitivity and Signal-to-Noise Ratio (SNR): A HAMAMATSU professional high-performance photo multiplier tube (PMT) with low dark count and high sensitivity is used as detector, which has high sensitivity and SNR to photostatic signal, thus ensuring high accuracy and high resolution of test results.
3.Super computational function: Using PCS technology to measure the size of nano particles, we must be able to distinguish the fluctuation of nanosecond signal. The core component of the instrument is a high-speed photon correlate developed by ASIC. It has the ability of recognizing 6ns with high resolution and high signal processing speed. It can collect photons quickly and real-time and calculate the correlation operation, which lays the foundation for testing accuracy.
4.Stable optical system: The photon correlation spectrum detection system is composed of high-power semiconductor laser and optical fiber controlled by constant temperature, which not only has small size, but also has strong anti-interference ability and stability, and ensures the repeat-ability and stability of the test results.
5.High precision temperature control system: the precision of sample pool temperature control system and laser temperature control system is as high as (+0.1 C), which makes the measured sample and laser light source in a constant temperature state throughout the testing process, avoids the influence of temperature change on the testing results, and ensures the accuracy and repeatably of the testing;

7.Super-powerful analysis software: The inversion algorithm in the analysis software adopts the cumulative method recommended by international standards, as well as the commonly used non-negative least squares (NNLS) and Contin algorithms. The test results are in good agreement with the international authoritative products of the same kind.
8.New heat dissipation system: New N9 has a dual-flow design. The hot air is directly discharged from the instrument shell. The multiplier tube, laser, correlate and other important components are no longer affected by the hot air. The measured data are more accurate and stable, and the service life of these important components is greatly prolonged.
9. Automatic induction door: The new N9 is equipped with automatic opening and closing function of the coloration door. When the hand is close to the instrument, the sliding door will open automatically to facilitate the tester to take the coloration dish. When the hand is away from the instrument, the sliding door will close automatically
