Alternative stationary phases are being developed to solve the shortcomings of bead chromatography processes, namely high diffusional resistance leading to long processing cycles (4–6 h). Targeted lifetimes of 75–150 bind and elute cycles, taking sometimes years to achieve and requiring cleaning and respective validation, storage, and column unpacking and repacking, elevate costs and introduce increasingly unacceptable bioburden risks. Chromatographic membranes, due to intrinsically high mass transfer rates, overcome these limitations, enabling residence times of seconds and full lifetime utilization (75–150…
