Laserdiffraktiomittauksia

Laserdiffraktiomittauksia, often translated as laser diffraction measurements, is a technique used to determine the size distribution of particles in a sample. This method relies on the physical principle that when light, such as a laser beam, encounters particles, it scatters in different directions. The angle and intensity of this scattered light are directly related to the size of the particles.

In a typical laser diffraction instrument, a laser beam is passed through a sample containing the particles. Detectors are positioned around the sample to measure the intensity of the diffracted light at various angles. Smaller particles scatter light at wider angles, while larger particles scatter light at narrower angles. By analyzing the pattern of scattered light, a sophisticated algorithm calculates the relative proportions of different particle sizes present in the sample.

This technique is non-intrusive and can be applied to a wide range of materials, including powders, suspensions, and emulsions. It is a widely adopted method in various industries such as pharmaceuticals, food science, and materials science for quality control, research and development, and process monitoring. The results are typically presented as a particle size distribution curve, indicating the percentage of particles within specific size ranges.
