- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- March 17, 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Principles of method if other than guideline:
- Laser light scattering. The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure the size of particles. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern

Method
The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure the size of particles. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern.
Result
Analysis carried out after 2 minutes of ultrasonic treatment:
D10=10.748 µm
D50=33.564 µm
D90=78.228 µm
Reference
The analysis was conducted after 2 minutes of sample sonification.
Description of key information
Median Mass Diameter = 33.564 µm
Additional information
Laser light scattering method.
