Any other information on results incl. tables
The substance as received at the test facility was observed to be a medium, white crystalline powder with clusters. At 32x magnification under a microscope, the particles appeared to be irregular shaped crystals. Many of the larger particles were rectangular in shape, whilst the smaller particles were irregular in shape. At 400x magnification, the sample was observed to be made up of single crystalline particles.
Applicant's summary and conclusion
- Conclusions:
- The substance is a white powder.
- Executive summary:
The substance was visually observed to be a white solid powder. Under a microscope, the substance was observed to be made up of single crystalline particles.
