Conclusions:
For the sample Tetraamminepalladium (II) acetate a median particle size d(0.5) of 113.185 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 113.185 μm was determined for the sample of Tetraamminepalladium (II) acetate.

Description of key information

The median particle size d(0.5) of tetraamminepalladium (II) acetate was determined to be 113.185 μm.

Additional information

The particle size distribution of the test item was determined by the particle sizing instrument Mastersizer 2000 (Michael-Schulz 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. A median particle size d(0.5) of 113.185 μm was determined for a sample of tetraamminepalladium (II) acetate.
