Witryna4 lip 2024 · An interstitial impurity is usually a smaller atom (typically about 45% smaller than the host) that can fit into the octahedral or tetrahedral holes in the metal lattice (Figure 12.4. 1 ). Steels consist of iron with carbon atoms added as interstitial impurities (Table 12.4. 1 ). Witryna3.2 Inorganic Impurities Inorganic impurities are normally detected and quantified using pharmacopoeial or other appropriate procedures. Carry-over of catalysts to the new drug substance should be evaluated during development. The need for inclusion or exclusion of inorganic impurities in the new drug substance specification should be discussed.
