Rationale for reliability incl. deficiencies:
other: Not GLP study
Qualifier:
equivalent or similar to guideline
Guideline:
other: internal method based on official guideline
Version / remarks:
internal method based on official guideline
Deviations:
not specified
Principles of method if other than guideline:
The sample was dispersed, stirred and ultrasonicated prior the analytical characterisation by light scattering.
