WebJun 3, 2013 · Laser diffraction has been the most common particle size analysis technique for many years. The technique is fast, flexible, and easy to use for a wide variety of sample types. Knowledge of the sample and dispersing medium refractive index (RI) is often required to generate the most accurate results when using laser diffraction. WebHave output between 1 and 5 times the Class 1 AEL for wavelengths shorter than 0.4 or longer than 0.7, or less than 5 times the Class 2 AEL for wavelengths between 0.4 and 0.7.

WebParticle size analysis — Laser diffraction methods 1 Scope This document provides guidance on instrument qualification and size distribution measurement of particles in many two-phase systems (e.g. powders, sprays, aerosols, suspensions, emulsions and gas bubbles in liquids) through the analysis of their light-scattering properties. WebIncident laser light is scattered or diffracted by particles. The diffraction angle depends on the particle size. Large particle scatter light to smaller angles, whereas smaller particles scatter light to larger angles. By analyzing an angle-dependent scattered light pattern, the particle size distribution can be calculated.
