LPA-156W Automatic Laser Diffraction Particle Size analyzer is an intelligent fully automatic laser particle size distribution analyzer with a fully sealed metal shell and good electromagnetic shielding and anti-interference performance. The detector and optical system are independently designed by Shuoboda, and the intellectual property rights of the full set of hardware and software are owned. The optical components, circulation system, etc. are placed inside the instrument to shorten the flow time of the sample in the pipeline, avoiding stratification and re-agglomeration of the sample after dispersion. Fully automatic sampling system and multi-functional testing software achieve accurate and fast testing.
According to GB/T19077-2016 ISO13320 and other standards, Mie scattering, diffraction principle and Shuoboda's (unconstrained) free distribution mode are used to calculate the particle size distribution, ensuring that each level of particle size reaches the highest resolution, fully detecting the subtle differences in the details of each particle level, so that it has extremely high resolution in the full range test, which has been highly praised by users. It is particularly suitable for particle size analysis in many industries such as papermaking, calcium carbonate, battery materials, chemicals, powder coatings, etc.
Scientific research institutions, electronic materials, powder coatings, papermaking, chemicals, ceramics, building materials, manganese carbonate, pesticides, pigments, medicines, cement, titanium dioxide, water-coal slurry, cosmetics, abrasives, food, calcium carbonate, talc, kaolin, alumina, rare earth, catalysts, foaming agents, refractory materials, graphite, marine sediments and other industries for particle size distribution testing of solid powders and emulsion slurries.

1. The inverted Fourier optical system is adopted to greatly reduce the stray light generated by multiple reflections of the sample pool and the optical mirror. The large-angle scattered light is not limited by the lens aperture, which effectively improves the test resolution and ensures the accuracy of the test data.
2. The 98-level multi-element detector completes the reception of forward and side scattered signals. The scattered signal detection is fine and the detection resolution is high. Each level of the detector background light is independently compensated to achieve the highest gain, the signal is collected and amplified at high speed, the dynamic response is sensitive and fast, and the optical path center self-check is completed at the same time.
3. Imported semiconductor laser, dual light source test resolution is higher, the main light source wavelength is 650nm, 30mw, and the life is >70000h. The auxiliary light source wavelength is 405nm, 20mw. The auxiliary light source plays a complementary role in improving the resolution of the small particle size range.
4. The elastically supported high-rigidity optical structure and stable optical path ensure that the instrument is in a stable state for a long time.
5. The sample detection pool is made of high-quality optical glass bonding to ensure the highest optical accuracy and mechanical strength, and long service life.
Integrated design, no need to disassemble
The instrument adopts a simple electromechanical integrated design. The circulation injection system is inside the instrument. You only need to add samples to the sample pool to automatically complete the test, saving operation time. The large-diameter ultrasonic dispersion pool and agitator mix evenly and quickly, so that the sample is fully dispersed and the bubbles are discharged quickly. The peristaltic pump pipelines are all of equal cross-section and flow rate, which ensures the accuracy and repeatability of the instrument test.
Perfect preparation system
It has intelligent functions such as automatic water absorption, automatic centering, automatic testing, automatic cleaning, and ultrasonic anti-dry burning. The unique fully automatic sample stirring motor device fully disperses the sample while reducing bubbles and liquid splashing, ensuring stable and reliable test results.
Stable dispersion system
The standard sample pool with a volume of 500ml is made of 304 stainless steel, which is durable and corrosion-resistant. The built-in automatic water suction pump can automatically fill water without manual operation. A water level detector is installed above the sample pool. When the water level reaches the specified height, the solenoid valve automatically closes to ensure the accuracy of each test medium. Because dispersion and circulation are completely independent, the cycle test time is short, which reduces the sample's adhesion, contamination and wear on the optical test dish, and improves and extends the service life.
