IF4164 Particle Sizing Systems

Povzetek

The size of a single particle is called “particle size”, and in some literature or test reports, it is also called “particle size” oz “particle size”, “particle size” and so on. The particle size of an individual particle in a particle group is the basis of particle size distribution. To accurately understand the particle size distribution, we must first understand the particle size. Zato, many users will also call the particle size meter.

Scientific research and technological innovation achievements

(1) The abnormal change of Airy spot (ACAD) and its influence on particle size measurement were found, and the interference of ACAD phenomenon on the inversion of light energy data was solved.

(2) Original polarization space filtering technology.

(3) Oblique trapezoidal window technology.

(4) The unified scattered light energy inversion algorithm eliminates the problem that users have to choose inversion modes, and different modes have different results.

(5) Distributed system dual motor drive and continuous monitoring of liquid level.

Working principle
1. The full-range Mi scattering theory is adopted for laser particle size analysis, which fully considers the refractive index of the dispersion medium and the measured particles, and inverts the particle size and particle size distribution law according to the changes of scattered light intensity of particles with different sizes at various angles.
2. The laser particle size analyzer adopts the original unconstrained fitting inversion method and spectrum amplification technology, which can obtain a more real distribution situation after data processing, which has very important practical value for scientific research customers such as universities and research institutes;
The test of nanoparticles must use the “dynamic light scattering” tehnologija, and the important part of this technology – correlator has been monopolized by foreign countries, nano laser particle size analyzer has taken the lead in breaking the international monopoly of this technology, filling the technical gap for the domestic, can test 1-3500nm size particles.

The laser particle size analyzer adopts wet dispersion technology, which has the advantages of simple operation and intuitive output data. Compared with the traditional instrument, the aging and analysis accuracy are improved. The instrument has shown a good prospect of popularization and application in the Yellow River hydrologic sediment particle analysis, such as the Yellow River water and sediment transfer experiment, the Xiaobei Main Stream silting experiment, and the Xiaolangdi Reservoir weight current test, and has played a great role.
