- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- November 27, 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Laser Light Scattering. The particle size distribution was analysed using the Mastersizer 2000 tool, which used 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 analysed to calculate the size of the particles that created the scattering pattern.

Method
The particle size distribution was analysed using the Mastersizer 2000 tool, which used 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 analysed to calculate the size of the particles that created the scattering pattern. The analysis was carried out after two minutes of sample sonication.
Results
D10 = 3.089 µm
D50 = 6.859 µm
D90 = 14.825 µm
Reference
The analysis was done after two minutes of sample sonication.
Description of key information
