Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- May 2, 2016
- 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
In order to measure the particle size distribution, the technique of laser diffraction (laser light scattering) was used 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 particle size distribution based on the scattering pattern. - GLP compliance:

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 value is 5.193 µm
D50 value is 25.995 µm
D90 value is 63.639 µm
Reference
