The median particle size L₅₀D (v, 0.5) of solids or liquids is the particle size defining the value at which 50 % of particle volume or particle mass is present with a lower particle diameter.

The particle size L₁₀D (v, 0.1) of solids or liquids is the particle size defining the value at which 10 % of particle volume or particle mass is present with a lower particle diameter.

The particle size L₉₀D (v, 0.9) of solids or liquids is the particle size defining the value at which 90 % of particle volume or particle mass is present with a lower particle diameter.

The particle size of a particle is given in µm.

	Measurement 1 [µm]	Measurement 2 [µm]	Average [µm]
L10	11.588	11.576	11.6
L50(Median particle size)	114.247	119.293	116.8
L90	482.313	505.565	493.9

Conclusions:

The determined average particle size ranges were L10D: 11.6 µm, L50D: 116.8 µm, L90D: 493.9 µm.
