In this study, inhalable HCQ powders were prepared and characterized for potential COVID19 therapy. Methods: Hydroxychloroquine sulfate (HCQsul) was jet milled (JM) followed by conditioning by storage at different relative humidities (43%, 53%, 58%, and 75% RHs) for 7 days. The solidstate properties, including particle morphology and size ...
Particle Size Distribution by Laser Diffraction. Enquire Now ← Return to Techniques. The instrument used is a Malvern Instruments Mastersizer MS2000. Any material present in the sample greater than 500 µm in diameter has to be manually sieved out of the sample prior to analysis by laser diffraction.
Micronization is a commonly used method for PSD. It allows reduction of the API particle to a micrometer size. This technique helps process heatsensitive products, because the temperature remains relatively constant throughout the process. Polpharma API has two jetmill micronizers, one in its manufacturing plant and one in the pilot plant.
That is, the product generated in the Magotteaux Mill® has nominally the same physical properties (particle size distribution) and pulp chemical properties (Eh, pH, dissolved oxygen, oxygen demand and EDTA extractable iron) as an equivalent sample taken from the plant.
