Optical microscope analysis
observed to be large solid free flowing lumps that are up to 40 mm in
using 3.2 objective lens
< 2000 µm were used. The particles appeared to be irregular amorphous

The test substance was found to be a solid
block with few broken bits. Due to the small amount of material < 2000
µm present in the test substance it was not possible to carry out
particle size distribution by laser diffraction.
A study was conducted to determine the
particle size distribution of the test substance (Purity: 100%), by
optical microscopic and manual sieve analysis. Under the study
conditions, the particle size for >99.95% by weight of the test
substance was determined to be >2000 µm (Chilworth, 2017).
The particle size distribution of the test
substance was determined by optical microscopic and manual sieve
analysis method (Chilworth, 2017).
Value used for CSA: >99.95% by weight
of the test substance were determined to >2000 µm.
