Conclusions:

Based on the present test conducted to determine the particles size of the test substance by sieving the substance contains only particles that are between 500 and 100 µm in size. No particles under 100 µm size were detected.

Executive summary:

The particle size of ferrous monoglycinate sulfate was determined by sieving the substance with an analytical sieve machine containing different sizes of sieves. No Particles were found below a size of 100 µm.
