Particle Size Analysis - Laser Diffraction Methods
Also Known As:
A standard called BS ISO 13320:2020 offers instructions on how to quantify particle size distribution using laser diffraction techniques. It can be used with many different kinds of particles in two-phase systems, including liquid gas bubbles, suspensions, sprays, aerosols, and powders. According to the standard, the size distribution of the particles is determined by examining their light-scattering characteristics.
The standard includes a broad range of particle sizes, beginning at around 0.1 mm and going up to 3 mm. Additionally, it states that the size range can be expanded to include both sizes above and below 0.1 micrometers with proper equipment and environmental factors. This exemplifies how flexible and adaptable the laser diffraction method is for analyzing particle size.
It is significant to note that the standard's optical model takes a spherical particle shape into account. Therefore, a size distribution based on the anticipated scattering pattern for the volumetric sum of spherical particles that matches the measured scattering pattern is presented for both spherical and non-spherical particles. In particular for non-spherical particles, the resulting particle size distribution may vary from those obtained by other methods based on other physical principles, such as sedimentation or sieving.
