High-tech enterprises, software enterprises, China science and technology exposition, Shandong materials industry enterprises, 75 national key project of science and technology, Shandong 85 key projects of science and technology, Shandong 95 key projects of science and technology, “ JL9300 powder laser particle size analyzer ” responsible person, the State Education Commission instrument research project “ YP750 spatial spectrum demonstration instrument  responsible person"

The full range of MIE scattering theory application in the laser particle size analyzer, MIE scattering theory is the highest theoretical basis and measurement and calculation method for micron and sub-micron particles, suitable for any large and small particles of the test, and taking into account of the small particles have absorption effect to the laser, and the problem of the refractive index. 
Fraunhofer diffraction theory have not concerned with absorption of small particles of the laser, it is suitable for large particles test.
The combination of the two theories is difficult to establish, therefore, whether the full range of MIE scattering theory is an important indicator of the advancement of laser particle sizer and detecting small particles.

With the original unconstrained free fitting inversion patent technique, more realistic particle size distribution can be obtained, such as free distribution, R-R distribution and so on. Unconstrained fitting inversion technique with automatic resolution of multiple peak particle swarm, without restriction of any functions, the analysis results entirely depend on the distribution of the scattering spectrum, maximize the fitting precision for all samples, truly reflect the distribution state of all the samples. There are twelve levels of granularity below 2um with high Physical resolution. The general inversion software test uses the function simulation calculation, not the real measurement value, result in the testing performance of laser particle size analyzer will greatly reduced.

Using convergent light Fourier transform patent technology, make the large angle scattering light not be restricted by Fourier lens aperture, effectively improve the laser particle size analyzer resolution, change measuring range without replace lens . Sealed stable light path, good dust-proof performance.
He-Ne Laser, Power≥2mW, wavelength :632.8nm
Good monochromaticity, Short wavelength, Narrow linewidth,  frequency-stabilized
Full scale test, Gear-shift test & Customized service 
Gear shift-laser particle size analyzer is with 2-3 gears, and there is a cross between the gears, It is not a sectional test. The user can select the appropriate gear according to the sample size. The advantage of Gear-shift is that a smaller measuring range can use the entire detection unit, and the testing accuracy is much higher than similar products of other factories.

Liquid particle size analyzer adopt integral structure design, built-in dispersed system includes ultrasonic vibration, mechanical agitation and electromagnetic pump cycle. The dispersion system make particles be always suspended in the pipeline, adjustable ultrasonic time, ultrasonic dispersion and particle test can be carried out simultaneously, avoid sample 2rd reunion after good ultrasonic dispersion, Shortening pipeline, easy and good dispersion, avoid large particles 2rd precipitation in the pipeline, after one measurement, the circulation system will return samples to the sample bucket for dispersion again, then could repeat test for get the stable data. For dry laser particle size analyzer, Dry dispersion system are composed of fully sealed sample cuvette patent and unique turbulent dispersion method, ensure the powders sampling will be fully dispersed...
