- Conclusions:
- A laser diffraction test was conducted to determine the particle size analysis of the test material. The analysis was carried out using the dry powder module and produced the following results:
Volume weighted mean: 405.833 μm
Median (d.50): 338.205 μm
Mode: 450.224 μm
MMAD (Mass Median Aerodynamic Diameter): 348.368 μm
10 % of material is < 45.981 μm
50 % of material is < 338.205 μm
90 % of material is < 862.898 μm
2.57% by volume of sample was seen to be < 10.00 μm. - Executive summary:
In a particle size distribution study (GLP106317R1V1/11) conducted using a laser diffraction method in accordance with ISO 13320:2009 and CIPAC MT 187 and similar to OECD Test Method 110, the test material was determined have a MMAD (Mass Median Aerodynamic Diameter) of 348.368 μm.
10 % of material is < 45.981 μm
50 % of material is < 338.205 μm
90 % of material is < 862.898 μm
2.57% by volume of the test meterial was seen to be < 10.00 μm.
