Materials and methods
Test guideline
- Qualifier:
- no guideline available
- Deviations:
- not applicable
- Principles of method if other than guideline:
- The particle size distribution is analysed by laser scattering analysis. Laser light interacts with the particles causing diffraction, refraction and absorption, thus producing a characteristic pattern of scattered light. If the particle size is significantly higher than the wavelength of the laser light predominantly diffraction patterns are produced. The principles of measurement are based on the Mie scattering theory.
- GLP compliance:
- no
- Type of distribution:
- other: laser diffraction
