![]() The data are evaluated using non-parametric statistical methods and considering the goodness-of-fit of the results.ĭetermination of particle size distribution profiles by laser diffraction is a common analytical technique utilized across multiple industries. Of interest is the expected overlapping region of each light source scattering pattern of the same particle size, studied by measuring the particle size distribution of narrowly dispersed standards across the 0.300 μm to 100 μm range. ![]() This work is concerned with understanding how the instrument’s internal algorithms account for both red and blue light sources to accurately determine particle size distribution profiles. Mie Theory is a rigorous solution for the scattering from a spherical, homogeneous, isotropic and non-magnetic particle based on the properties of a collimated, monochromatic light source. The wide range of the instrument is also achieved using mathematical algorithms based on laser diffraction theory, such as Mie Theory. For a commonly used laser diffraction instrument, the wide dynamic range is accomplished by using a sequential combination of measurements with red and blue light sources. ![]() Due to its simplicity and precision, laser diffraction is an analytical technique frequently used in the determination of particle size distribution profiles.
