Any other information on results incl. tables
Visual and microscopic evaluation of the sample:
1. standard visual observation
- sample observed to be polydispersed (coarse, medium, fine and gritty particules) with clusters
2. microscope analysis (100x magnification)
- the particles appeared to be irregular shaped crystals
- the smallest individual particle size was approx. 16.0 µm and the largest individual size was approx. 1024 µm
3. microscope analysis (400x magnification)
- sample was observed to be made up of both single and agglomerated crystalline particles
Applicant's summary and conclusion
- Conclusions:
- The MMAD of the test substance was determined to be 110.747 µm using Laser Diffraction Particle Size Analysis with a 'wet', small volume dispersion system. The median (D50) was determined as 85.443 µm. 4.04 % by volume of sample was seen to be < 10.00 µm.
