Visual and microscopic evaluation of the sample:

1. standard visual observation

- sample observed to contain coarse, gritty, medium and fine particulates which form clusters

2. microscope analysis (100x magnification)

- the particles appeared to be irregular shaped crystals

- the smallest individual particle size was approx. 3.2 µm and the largest individual size was approx. 432 µm

3. microscope analysis (400x magnification)

- sample was observed to be made up of both single and agglomerated crystalline particles

11.66% by volume of sample was seen to be < 10.00 µm.

Conclusions:

The MMAD of the test substance was determined to be 116.98 µm using Laser Diffraction Particle Size Analysis with a 'wet', small volume dispersion system. The median (D50) was determined as 89.197 µm. 11.66% by volume of sample was seen to be < 10.00 µm.
