Particle size distribution by laser diffraction (solid samples)

Determination of particle size distribution (PSD) by laser diffraction (LD). The analysis is performed on solid samples. The method can analyze particle sizes from ~0.4 µm to 2000 µm.

The test report will include a particle size distribution graph, values for volumetric mean = D[4,3], and the following percent finers (percent finers represent the amount of the material that is smaller than a certain size):

• Dv(10) / D(v,0.1) / 10 %

• Dv(25) / D(v,0.25) / 25 %

• Dv(50) / D(v,0.5) / 50 % = median

• Dv(75) / D(v,0.75) / 75 %

• Dv(90) / D(v,0.9) / 90 %
