WebJan 15, 2009 · The control of crystal size distribution (CSD) in pharmaceutical crystallization is of primary importance, as downstream processes such as filtration or … WebThe crystal size distribution at time t, n(L, t), provides a quantitative measure of the number of crystals of size L in a unit magma volume. It is a population density function, hence the number of crystals of size between L and L + dL in a unit sample volume is n(L, t)dL (e.g. Marsh, 1998, 2007).

WebJun 1, 2024 · The first method is to obtain a small crystal size distribution [24], [25], [26]. This mainly causes the drug to have a faster delivery rate. The second method is to obtain a large crystal size distribution [27], [28]. This mainly enhances the efficiency of downstream operations. WebMar 13, 2024 · It is often assumed that distributional properties of crystal size conform to the Gaussian distribution or the log normal distribution. The mean and variance or relative crystal number are widely adopted to describe the crystal size distribution and taken as the control objectives.
