Conclusions:
The particle size distribution of ammonium dihydrogenorthophosphate was determined by laser diffraction analysis-'wet' small volume dispersion system (GLP-compliant study in accordance with OECD 110, ISO 13320 and CIPAC MT 187). 1.99 % is < 10.00 μm; 10% is < 149 µm; 50% is < 354 µm and 90% is < 666 µm.

Description of key information

The particle size distribution of ammonium dihydrogenorthophosphate was determined by laser diffraction analysis-'wet' small volume dispersion system (OECD 110, ISO 13320, CIPAC MT 187 and GLP). 2% is < 10.00 μm; 10%  is < 149 µm;  50% is < 354 µm and  90% is < 666 µm.
