Description of key information

The median particle size L50 = 150.8 µm

Additional information

The particle size distribution of a dedusted formulation of Disperse Blue CVG was measured at its production site by laser diffraction (light scattering) by means of a Beckman Coulter LS Particle Size Analyzer.

The distribution between these particle sizes are the following:

<23 μm

<31 μm

<46 μm

<75 μm

<101 μm

<201 μm

<281 μm

<501 μm

The median particle size L50(D (v, 0.5): 50 % of particle volume or particle mass with lower particle diameter) deduced from these distributions are: L50 = 150.8 µm

The particle size L10(D (v, 0.1): 10 % of particle volume or particle mass with lower particle diameter) deduced from these distributions are: L10= 56.35 µm

The particle size L90(D (v, 0.9): 90 % of particle volume or particle mass with lower particle diameter) deduced from these distributions are: L90= 245 µm

 

The particle size distribution of the milled press cake produced for registration studies was determined by laser diffraction (light scattering).

The median particle size L50 of the test item deduced from the particle size distributions was 18.5 µm.

The particle size L10 of the test item deduced from the particle size distributions was 2.0 µm.

The particle size L90 of the test item deduced from the particle size distributions was 197.5 µm.
