- Executive summary:
The size distribution of particles present in the test item was assessed using apparatus based on laser diffraction. The study was designed to be compatible with the following guidelines and recommendations: CIPAC MT 187 and BS ISO 13320:2009. The particle sizer used was the Malvern Mastersizer 3000 (with associated software). Stirrer speed was 2400 rpm and the size range was 0.01 to 3500 microns. Initially a sample of the test item was examined using a microscope in order to describe the morphology of the particles. To determine the particle size distribution, a beaker of dispersant was placed in the sampling unit and the sampling head inserted into the solvent. Test item (approximately 200 mg) was transferred to the contents of the beaker and the measurement process started. Measurements were taken until the results were at equilibrium – three measurements per sample were recorded. The final measurement for each sample being taken as the reported result. The particle size distribution assessment was performed in duplicate.
The test item was described as a fine crystalline powder when examined using a microscope. d(0.1) is the diameter where 90% of the distribution is above and 10% is below. d(0.5) is the diameter where 50% of the distribution is above and 50% is below. The is referred to as the Mass Median Diameter (MMD). d(0.9) is the diameter where 10% of the distribution is above and 90% is below. The overall mean values for the 10, 50 and 90% quantiles were 12, 78, and 290 µm, respectively.
