Purification of bioproducts by a bioseparations process typically involves a long sequence of steps, and each step requires the use of one or more unit operations, such as filtration, extraction, chromatography, and drying. This article gives an overview of bioseparations, including two examples of basic principles and theory for two key unit operations — filtration and liquid chromatography.
