Particle sizeopen allclose all
Percentile:
D50
Remarks on result:
other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
Percentile:
D10
Mean:
346 µm
Remarks on result:
other: The determination of a standard deviation of the particle size distribution is not possible due the fact the maximum of the distribution is in the fraction above 1400 µm
