Applicant's summary and conclusion
- Conclusions:
- The median particle size D50 of the test item deduced from the particle size distributions was : 19.36 micrometer.
The particle size D10 of the test item deduced from the particle size distributions was : 2.730 micrometer.
The particle size D90 of the test item deduced from the particle size distributions was : 63.99 micrometer. - Executive summary:
The particle size distribution of magnesium gluconate was determined following ISO 13320 (Particle size analysis - Laser diffraction methods).
The particle size distributions were determined in a test serie. For the test serie fraction (left axis of the ordinate) and the shiftings (right axis of the ordinate) are presented in percent by volume as a function of the particle size. Median value was calculated from unrounded values.
The median particle size D50 of the test item deduced from the particle size distributions was : 19.36 micrometer.
The particle size D10 of the test item deduced from the particle size distributions was : 2.730 micrometer.
The particle size D90 of the test item deduced from the particle size distributions was : 63.99 micrometer.
