Abstract

The invention provides a packing method for high efficiency chromatography columns starting from dry swellable particles, as well as columns packed by the method and the use of the columns in separation of biomolecules. In the packing method, an amount of dry swellable particles sufficient to give a swollen volume in a liquid of about 105-120% of the column chamber volume is transferred to the column, the column is closed and the liquid is provided to the column.
