Screen Analysis by Laser Diffraction

 Screen Analysis by Laser Diffraction

According to the principle of light scattering, we measure the size of particles. The test methods are mainly divided into static light scattering method and dynamic light scattering method. The dynamic light scattering method is mainly to determine the size of the particles by measuring the intensity change of the scattered light of the diffused particles when they perform Brownian motion in a liquid suspension solution. The larger the particle, the slower the Brownian motion. The static light scattering method mainly analyzes and determines the light intensity received at different angles. The experts can accord to the characteristics of the samples, and can choose suitable measurement methods to deal with and solve the detection of rare earth powder materials of any size encountered by customers. The employees of Alfa Chemistry have rich experience and solid professional knowledge, which can help analyze data and help customers make more appropriate decisions.


Our Services

The particle shape of powder materials usually has a significant impact on the performance of the product. On the assumption that all particles are spherical, the shape can be used as an important detection basis for confirming light scattering analysis. The advanced instruments of Alfa Chemistry can use high-resolution cameras to capture images of particles, and then calculate their particle size distribution and other parameters. The light scattering services that A can provide include but are not limited to:

❖ Dynamic light scattering (DLS) particle size determination

❖ Static light scattering method to measure particle size
