Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: CTL SOP No. 417 Particle Size Analysis
- Principles of method if other than guideline:
- The analysis is conducted initially using a visual microscope and is then undertaken more formally using a Laser Diffraction Particle Size Analyser. The benefit of this procedure is that it allows the operator to obtain a better understanding of the particle characterisation of the material. This includes, but is not limited to, sample clusters and agglomerations which may provide false values in the formal particle size analysis. In these situations, where the operator can assess how easily these clusters or agglomerations are dispersed, ultrasonics may be employed. Owing to the extremely small quantities of material used in this analysis it should be noted that discrepancies can arise between the lower and upper limits of the particle size and the actual value obtained in the formal particle size analysis.
- GLP compliance:
- yes (incl. QA statement)
- Type of distribution:
- mass based distribution

Standard visual observation: Sample observed to be a polydispersed green powder with lumps and clusters.
Observation at 100 x magnification: The particles appeared to be irregular shaped crystals. The smallest individual particle size was approximately 3 μm and the largest individual size was approximately 70 μm.
Observation at 400 x magnification: The sample was observed to be made up of single crystalline particles and agglomerated particles.
Applicant's summary and conclusion
- Conclusions:
- The 10th, 50th and 90th percentile of particle diameter are 1.257, 3.123 and 9.030 µm, respectively. Coefficient of variation for d50 is less than 3%; d10 and d90 are less than 5%. Thus repeatability of the characteristic particles in the size distribution are within the acceptable limits as per the ISO 13320-1 test standard.
