Particle size distribution by laser diffraction (dry mode analysis)
Determination of particle size distribution (PSD) by laser diffraction (LD). The analysis is performed on powder samples in dry mode (i.e., without dispersion). The method can analyze particle sizes from ~0.4 µm to 2000–3500 µm. The analysis is performed according to ISO 13320.
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 %
Additional statistical data can be included in the report.
The following tools are used for the analysis:
Beckman Coulter LS230
Malvern Mastersizer 2000 and 3000 (with Scirocco 2000 or Aero S add-on)
