Materials and methods
- Principles of method if other than guideline:
- The samples were examined by laser diffraction in order to determine the Mass median aerodynamic diameter (MMAD); this is also known as the geometric mean aerodynamic diameter.
The analysis was carried out using the Coulter LS230 Laser Diffraction Particle Size Analyser fitted with the Dry Powder Module. The analysis was carried out 5 times. 3 of the 5 runs were then averaged to produce the results in the table below.
Optical Model: The calculation of particle size requires optical values of the material for increased accuracy; for this work we used a refractive index of 1.645 (determined by immersing the material in refractive index matching oils) and an imaginary component of 0.0. - Type of method:
- Laser scattering/diffraction
- Type of distribution:
- mass based distribution

Applicant's summary and conclusion
- Conclusions:
- The laser diffraction tests performed to conduct particle size distribution studies on two batchess originating from different producers of the substance Antimony Potassium Tartrate, indicate a mass median aerodynamic diameter of 46.0 - 52.1 micrometers. A maximum of 5.14% of the particles have a diameter below 10 micrometers, corresponding to the respirable fraction.
