The use of particle characteristics to elucidate mix homogeneity in binary powder blends.
A series of binary powder blends comprising microcrystalline cellulose (Avicel PH101), alpha-lactose monohydrate, or anhydrous theophylline were prepared in order to investigate the ability of particle-characteristics measurements to express the homogeneity of the resulting mixture. It is postulated that fundamental physical characteristics, such as particle-specific surface area, true density, and size distribution, can be used to quantitatively ascertain mix homogeneity in routine pharmaceutical blending operations.
