Description of key information

Barium sulphate standard: MMAD 53.84 µm GSD 2.12 µm
Barium sulphate standard: D50 1.16 µm (Laser diffraction)
Barium sulphate fine powder: MMAD 42.25 µm GSD 3.04 µm
Barium sulphate fine powder: D50 2.6 µm (Laser diffraction)

Additional information

The measurement was not performed under previous suspension of the substance. As the fine powder agglomerates under air (humidity), the D50 of the fine quality is higher than the D50 of the standard powder.
