Product advantages
- PA-1155 laser particle size analyzer is an economical and practical fully automatic laser particle size distribution analyzer. It calculates particle size distribution based on GB/T19077-2016, ISO13320 and other standards, Mie scattering and diffraction principles, and adopts the (unconstrained) free distribution mode of LabGenito ensure that each level of particle size reaches the highest resolution. The detector and optical system are independently designed by LabGeni, and the whole set of hardware and software have independent intellectual property rights.
- The fully sealed metal shell has good electromagnetic shielding and anti-interference performance. The optical components and circulation system are set inside the instrument, so that the sample flows in the pipeline for a short time, avoiding stratification and re-agglomeration after the sample is dispersed. The test time is about 1 minute, and it can be tested once or multiple times, with high data repeatability and good stability. The instrument is particularly suitable for production enterprises and application enterprises with a single product type and a narrow distribution of powder particle size.
Test Principle
Laser particle size analyzer is based on the principle of laser scattering, through laser , Fourier lens, photoelectric receiver, sample dispersion cycle, software data analysis and processing system to detect particle size distribution. Mie scattering theory shows that when the light beam is blocked by particles, A part of the light will be scattered, and the propagation direction of the scattered light will form an angle θ with the propagation direction of the main beam. Theta angle The size is related to the size of the particle. The larger the particle, the smaller the θ angle of the scattered light (Figure 1); The smaller the particles, the more The scattered light θ The larger the angle (Fig. 2).
That is, the scattered light at a small angle (θ) is caused by large particles, and the scattered light at a large angle (θ1) is caused by small particles. Further research shows that the intensity of scattered light represents the number of particles of that size. In this way, the intensity of scattered light at different angles is measured. The particle size distribution of the sample can be obtained.
