Witryna7 kwi 2024 · As solids are restricted in atomic motion, there is little difference in entropy between a pure and impure solid. However, there is a more significant difference in entropy between a pure and impure liquid, and an impure liquid has greater disorder and greater entropy. Witryna3 wrz 2024 · Determination of impurity contents is one of the main issues with quality control of drug substances and medications. Formulas in which peak areas of identified impurities are multiplied or divided by special correction factors, usually designated as F ( CF) or RRF, are usually used for the calculations.
