The concept of measuring CV/h is especially useful in affinity chromatography where the residence time determines the capacity independent of scale or bed height. In a recent multidimensional scale-up study, CV/h was used to perform a 20-fold scaling from lab- to pilot scale. It is also useful for many ion exchange, … See more Keeping a constant residence time is a well-established strategy when scaling up a chromatography step. Typically, this is achieved by keeping the bed height and linear flow velocity … See more Rather than strict adherence to constant linear velocity (cm/h), you can try measuring column volumes per hour (CV/h) for increased flexibility (1).
