Materials and methods
Test guidelineopen allclose all
- Qualifier:
- according to guideline
- Guideline:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 187
- Principles of method if other than guideline:
- he analysis was conducted initially using a visual microscope and was then undertaken more formally using a Laser Diffraction Particle Size Analyser. The sample was observed under 3 conditions: Direct observation, under a microscope with 32 x magnification, under a microscope with 400 x magnification. The physical characteristics of the material were recorded, noting such items as shape and size distribution. Following this the Malvern Mastersizer 2000 Laser Diffraction Analyser was used. Five runs of the method were conducted to ensure repeatability of results.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- primary particle
- Type of distribution:
- volumetric distribution

Standard visual observation:
Sample observed to be a fine and medium size, white crystalline powder.
Observation at 32 x magnification:
The particles appeared to be irregular shaped crystals. The smallest individual particle size was approximately 19 µm and the largest individual size was approximately 576 µm.
Observation at 400 x magnification:
The sample was observed to be made up of single crystalline particles.
Applicant's summary and conclusion
- Conclusions:
- The mass median aerodynamic diameter was determined to be 276.5 um.
