Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: Laser scattering (Mie scattering theory)
Deviations:
not specified
Principles of method if other than guideline:
In general, the scattering of the incident light gives distinct pattern which are measured by a detector. The particle size distribution of test substance was determined by a particle size analyzer GSL-101BI. Details refer to report attached.
GLP compliance:
no
Type of distribution:
volumetric distribution
