Theoretically, scale-up is elegantly achieved by increasing the diameter of a column (1–2 m), maintaining the same linear velocity, and keeping the bed height a constant to assume a uniform flow distribution.

WebMay 26, 2006 · The key to understand scale-up is the concept of time scales. The time scale tells how fast a process is. Small time scales mean fast processes. The time scales involved are the time scales for flow, mass transfer, and dispersion. When scaling up or scaling down, processes of similarity will be processes, which have identical time scales [1]. 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). This approach gives … See more Let’s put this alternative approach to the test. As an example, assume we want to do a 300-fold scale-up of mass load starting with a column with a diameter of 26 mm. To simplify, we leave out any scale-up steps … See more
