- Conclusions:
- Using the laser diffraction test (‘wet’, small volume dispersion system), the Mass Median Aerodynamic Diameter (MMAD) of magnesium nitrate was determined to be 115.666 µm. Furthermore, it was determined that 17.86% by volume of sample was seen to be < 10.00 ?m
- Executive summary:
Using the laser diffraction test (‘wet’, small volume dispersion system), the Mass Median Aerodynamic Diameter (MMAD) of Magnesium Nitrate was determined to be 115.666 µm. Furthermore, it was determined that 17.86 % by volume of sample was seen to be < 10.00 µm
Reference
17.86 % by volume of sample was < 10.00 µm.
Volume weighted mean is 82.592 µm.
Description of key information
The particle size distribution is specified by:
Mass Median Aerodynamic Diameter 115.666 µm
D50 = 71.733 µm
Volume weighted mean: 82.592 µm
Additional information
Particle size distribution was determined according to OECD Guiline 110 under GLP with the mass median aerodynamic diameter being 115.666 µm and the D50 = 71.733 µm (Chilworth 2010).
