Applicant's summary and conclusion
- Conclusions:
- The results of the laser diffraction test conducted to determine the particle size of v182675 are summarised in the table below. The analysis was conducted on the fraction of the sample which was < 1000 μm using the small volume (wet) module (SVM) with acetonitrile as the dispersant.
Particle Size Analysis using small volume module (SVM) Average (μm)
Volume weighted mean 356.153
Median 368.335
Mode 492.842
MMAD (mass median aerodynamic diameter) 418.348
d10 - 10 % of material is < 4.599
d50 - 50 % of material is < 368.335
d90 - 90 % of material is < 717.763
volume of sample < 10.00 μm 19.14%
