Conclusions:
For the sample Palladium (II) nitrate hydrate a median particle size d(0.5) of 69.445 μm was determined.
Executive summary:

The particle size distribution of the test item was determined by the particle sizing instrument Mastersizer 2000. This study is considered suitable for use as the key study for this endpoint. A median particle size d(0.5) of 69.445 μm was determined for the sample of Palladium (II) nitrate hydrate.

Description of key information

The median particle size d(0.5) of Palladium (II) nitrate hydrate was determined to be 69.445 μm.

Additional information

The particle size distribution of the test item was determined by the particle sizing instrument Mastersizer 2000 (Michael-Schultz 2016). This is a non-GLP, non-guideline but well documented study and therefore is considered suitable for use as the key study for this endpoint. The median particle size d(0.5) of Palladium (II) nitrate hydrate was determined to be 69.445 μm.
