In pharmaceutics, micromixing is a process in which ingredient particles rearrange to form a blend.
Choice of materials is important to assure the flow characteristics, potency, and absorption of specific formulations.
In addition, proper particle size grades of the ingredients must be selected to produce an optimum blend for capsule filling.
In order to study the rate and uniformity of blending, destructive analytical methods, such as dissolution followed by chromatographic separation and detection are often used.
In addition to laboratory analysis, imaging of near line pull-samples has been used to indicate whether the mixing endpoint has been achieved.
