- Conclusions:
- Visual examination at 100x magnification showed irregular shaped crystals between approximately 3 µm and 16 µm.
The particle size distribution of T003421 determined by the laser diffraction method led to the conclusion that the average volume weighted mean based on 5 runs was 4.622 µm and the Mass Median Aerodynamic Diameter (MMAD) based on 5 runs was 4.285 µm, whereas the average D10, D50 and the D90 were determined to be 1.700 µm, 3.863 µm and 8.58 µm, respectively.
Reference
Visual Microscope Analysis
(1) Standard visual observation: sample observed to be a fine white crystalline solid with clusters and agglomerations.
(2) 100x magnification: particles appeared to be irregular shaped crystals (smallest +/- 3 µm and largest +/- 16 µm)
(3) 400x magnification: sample was observed to be made up of single crystalline particles.
Laser Diffraction Particle Size Analysis
Using the identified parameters, the particle size was analysed over the range 0.2 μm to 2000 μm.
The average Volume weighted Mean was 4.622 µm and the mode was 3.953 µm. The Coefficient of Variation for d50 was <3%; d10 and d90 were <5%. Thus the repeatability of the characteristic particles in the size distribution was within the acceptable limits according to the ISO 13320-1 test standard.
Description of key information
The particle size distribution of T003421 was determined by the laser diffraction method in a GLP study according to Chilworth Technology Ltd SOP n°417, ISO 13320:2009 and CIPAC MT 187 (Livingston, 2017). The visual examination at 100x magnification showed irregular shaped crystals between approximately 3µm and 16 µm. The MMAD was determined to be 4.285 µm, whereas the average D10, D50 and the D90 were determined to be 1.700 µm, 3.863 µm and 8.581 µm, respectively.
