Applicant's summary and conclusion
- Conclusions:
- Using the Dry Powder Module, the laser diffraction test conducted to determine the particle size analysis produced the following results (in average µm):
Volume weighted mean: 16.649
Median (d.50): 12.307
Mode: 13.686
MMAD (Mass Median Aerodynamic Diameter): 13.082
10% of material is < 4.134
50% of material is < 12.307
90% of material is < 27.943
