Laser particle analysis is a technique used to determine the size distribution of particles in a sample. It relies on the principle of laser diffraction, where a beam of laser light is scattered by the particles present. The angle at which the light is diffracted is inversely proportional to the size of the particle. Larger particles scatter light at smaller angles, while smaller particles scatter light at larger angles. A detector measures the intensity of the scattered light at various angles, creating a diffraction pattern. Sophisticated algorithms then analyze this pattern to calculate the distribution of particle sizes within the sample. This method is non-destructive and can be applied to a wide range of materials, including powders, suspensions, and emulsions. Applications are found in fields such as pharmaceuticals, food science, materials science, and environmental monitoring for quality control and research purposes. The accuracy of laser particle analysis depends on factors like particle shape, refractive index, and the presence of multiple particle populations.
