Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
June 23rd, 2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Study conducted according to internationally accepted testing procedures.
Reference:
Composition 0
Principles of method if other than guideline:
Laser light scattering. The test was performed according to the SOP - STR 071 protocol.
The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measures the size of particles. It measures 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.
GLP compliance:
no
