laserdiffraktiomittauksille

Laserdiffraktiomittauksille, commonly referred to as laser diffraction measurements, is a technique used to determine the size distribution of particles. This method relies on the principle that when a laser beam interacts with particles, it diffracts, scattering light in a pattern that is dependent on the particle size. Larger particles produce diffraction patterns with narrower angles, while smaller particles scatter light over wider angles.

The process typically involves passing a suspension or dry powder of the particles through a laser beam. Detectors are positioned around the sample to capture the scattered light. By analyzing the intensity and angular distribution of the diffracted light, sophisticated algorithms can calculate the volume-weighted particle size distribution. This technique is non-destructive and can be applied to a wide range of materials, including powders, suspensions, and emulsions.

Laser diffraction is widely used in various industries for quality control and research. Applications include measuring the size of pharmaceutical ingredients, pigments, food products, cement, and biological cells. The technique offers a rapid and reproducible method for particle size analysis, providing valuable insights into material properties, performance, and processing characteristics. Different models of laser diffraction instruments exist, offering varying levels of automation and detection capabilities to suit specific analytical needs.
