Product DescriptionSKZ1062F 1-10000um Test Range 90° Angle Nano Particle Size AnalyzerFeatureHigh-speed photon correlator and professional high-performance photomultiplier tube as the core device for fast, high resolution, repeatability and accuracy 1. Advanced test principle: Using dynamic light scattering principle and photon correlation spectroscopy technology, the particle size is determined according to the speed of Brownian motion of the particles in the liquid. The small particle Brownian motion speed is fast, and the large particle Brownian motion speed is slow. When the laser beam is irradiated on the moving particles, the scattered light at a certain angle (the instrument uses 90 degrees) changes dynamically with time. The speed of the change is related to the speed of the Brownian motion of the particles in the liquid. Photon correlation spectroscopy is used. The dynamic scattering spectra were statistically and correlatedly analyzed, and the particle size was calculated according to the Stokes-Einstein equation. 2. High sensitivity and signal to noise ratio:Using HAMAMATSU professional high-performance photomultiplier tube (PMT) with low dark count and high sensitivity as detector, it has high sensitivity and signal-to-noise ratio for photon signals, thus ensuring high accuracy and high resolution of test results.3. Superior computing capabilities:The determination of nanoparticle size using PCS technology must be able to resolve nanosecond signal fluctuations. The core component of the instrument is a high-speed photon correlator developed by an application-specific integrated circuit ASIC. It has a very high resolution of 6ns and a very high signal processing speed. It can collect photon numbers in real time and calculate related operations. 4. Stable optical path system:The photon correlation spectrum detection system constructed 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, and ensures stable and stable test results.SpecificationConcentration range0.1mg/L --100mg/LAccuracy<1%Repeatability error<1%LaserMain laser: λ=532nm, semiconductor laser (temperature control protection), P>30mWDetectorPhotomultiplier tube (PMT)Scattering angle90°Sample cell10mm*10mm , 4mlTemperature range5-90 ° C (accuracy ± 0.1 ° C)Rated voltageAC110V/ AC220VTest speed<1Min/time (excluding sample dispersion time)Photon correlatorPhysical channel: 512, equivalent channel: 10000, baseline channel: 8Sampling and delay time: 1us~200us dynamically adjustableMinimum resolution: 6nsPacking & DeliveryCompany ProfileFAQ
