A framework for the prediction of scale-up when using compressible chromatographic packings

Abstract

Experimental data are given for the solid pressure distributions in chromatography columns of various column aspect ratios packed with four types of agarose-based resin. The loss of column wall support at large scales can result in unexpectedly high pressures caused by the compression of the matrix via drag forces exerted by fluid flow through the bed. The need for an accurate model to predict flow conditions at increasing scale is essential for the scaling-up of chromatographic processes and for avoiding bed compression during operation. Several studies have generated correlations that allow for the prediction of column pressure drops, but they either are mathematically complex, which impai..
