Executive summary:

The particle size distribution of Copper glucoheptonate was measured with sieves (USP method).

The results were obtained as follows:

> 800 µm: 0.6 %

800 -200 µm: 39.64 %

200 -150 µm: 29.58 %

150 -100 µm: 20.32 %

100 -71 µm: 7.65 %

71 -63 µm: 1.81 %

63 -40 µm: 0.4 %

< 40 µm: 0 %

Additional information

The particle size distribution of Copper glucoheptonate was measured with sieves (USP method; Dabeer, 2014). The majority of the particles (89.54 % w/w) has a size between 100 and 800 µm. 9.86 % w/w of the particles are smaller than 100 µm but bigger than 40 µm.
