Applications
Measure the particle size distribution of powder or latex.
Measure the particle size distribution of powder or latex.
Principle
Light is an electromagnetic wave. When light meets with particles on it way of traveling, the interaction between light and particles will result in deviations of part of the light, which is called light scattering. The bigger the scattering angle is, the particle size will be smaller, the smaller the scattering angle is, the particle size will be bigger. The particle analyzer instruments will analysis the particle distribution according to this physical character of the light wave.

2. Optimized light path structure
l Light path system is fully-enclosed, dust-proof and it can prevent light pollution.
l Light path adopts lens back Fourier transform structure, the biggest acceptance angle isn’t restricted by the lens aperture, the backward detector can realize the extension of measurement lower limit to 0.1μm.
l Optical source adopts imported He-Ne laser emitter which owns better monochromaticity, high coherence, small divergence angle and better stability compared to other laser emitters.
l For laser emitter, except for traditional detection of output power value, we add the stability test of output power. We also adopt the patent design of integrated laser emitter (patent no.: 00228952.0) which reduces heat distortion of laser tube and external mechanical vibration.
l Smoothing processing technology is used to reduce the impact of laser emitter’s power fluctuation to measurement.
l The constant voltage and limited current, filling treatment technology reduce the probability of laser emitter flashing to extremely low.
l Spatial filter is fixed by super permanent magnet to protect the pinhole from skewing, which improves the stability of light path greatly, the new design eliminates the diffraction rings of laser effectively, the light energy data will be more accurate, it’s better for measuring large particles.
l Automated alignment device can realize more accurate alignment quickly, helps to prolong its service life. The accuracy of alignment can reach 0.5μm.
l Detector array adopts unique scattered light detection around a sphere surface (DAS) (patent no.: 95223756.3), the large angle detectors are placed in a spherical surface to get accurate focus of the large angle scattered light.
3. Advanced data collection and processing technology
l Using 8-channel simultaneous sampling to sample 16 bit ADC, the sampling frequency of frame data can reach 1 kHz.
l Using 64-channel simultaneous sampling technology and sample & hold switch with ultralow leakage current, the full scale accuracy can reach 0.15%.
l Firmware update and data configuration are available, more convenient for maintenance and operation.
l High-quality components, lower failure rate.
l Offset function of electric background, it can help to get more accurate optical energy data.
4. Friendly & practical software Functions:
l SOP standardization operating procedure function, it standardizes the analysis & testing process.
