Product Description New NKT-N9 is the latest nanometre
particle size analyzer based on dynamic light scattering principle
introduced by our company. It uses high-speed photon correlate and
professional high-performance photo-multiplier tube as the core
device. It has the characteristics of fast, high resolution, repeat
ability and accuracy. It is the preferred product for nano particle
size determination. New N9 has been completely new designed.
Products Characteristics Main performance characteristics:
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. 13.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; 6.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.Product
