- Conclusions:
- The mass median diameter (MMD) of FAT 40827/A was determined to be <5.5 µm.
- Executive summary:
The determination of the particle size distribution of FAT 40827/A was performed according to the European Commission, Part 5.2 "Laser scattering / diffraction" using the laser diffraction method. FAT 40827/A is a fine black powder. Under the microscope (with a magnification of 400) black globules of different sizes were observed. A solubility test showed, that the test item is both: sparingly soluble and well dispersible in 2-propanol. The particle size distribution of FAT 40827/A was performed with two samples of the stock dispersion each measured in duplicate. The individual measurements and the results obtained using the laser diffraction method of FAT 40827/A were determined. In conclusion, using the laser diffraction method to study the particle size of FAT 40827/A ranging between 0.3 µm and 300 µm, the mass median diameter (MMD) was determined to be <5.5 µm. The particle size distribution was found to range from approximately 0.3 µm to 24.0 µm.
