Sample Preparation in the Pharmaceutical Industry

In the analysis of solid material, the popular adage that “bigger is better” certainly does not apply. The goal is to produce particles that are sufficiently small to satisfy the requirements of the analysis while ensuring that the final sample accurately represents the original material. The “particles” of interest to the analyst generally range from 10 µm to 2mm. Additionally there are many application, where even finer sizes are needed. One example are active ingredients, where it is necessary to grind in the submicron range. Finally for DNA or RNA extraction mechanical cell lysis is well-established. Materials differ widely in their composition and physical properties. Hence, there are many different grinding principles that can be applied, and this, together with other variables such as initial feed or “lump” size, fineness needed and amount of sample available, results in a wide range of models available to the researcher.
