Abstract
A method for determining the concentration of a chromatographic medium in a liquid slurry comprises the steps of: providing a column (1) having a top end (3) and a bottom end (2) and adapted to retain a chromatographic medium therein; introducing a defined volume of the slurry (15) into the column (1); providing a liquid flow through the column (1) from the top end to the bottom end of the column to settle the chromatographic medium in the column; measuring the bed height of the consolidated chromatographic medium or a value related thereto; and determining from the measured bed height or value related thereto the concentration, or a value related to the concentration of the chromatographic medium in the slurry. A device for performing the method as well as the use of the method in packing of especially large scale columns are also disclosed.
