Abstract:
A method for recovering a desired component from a sample solution comprising the steps of(i) feeding the sample solution comprising the desired component to be recovered into a column containing beads having affinity for the component, through a bottom port equipped with a flow distributor, under stabilized fluidized bed conditions, whereby unbound components of the sample solution are discharged through the top port of the column, (ii) washing the column with a solution introduced through said bottom port under flow conditions, maintaining an expanded bed, whereby remaining solid components and other impurities of the sample solution are discharged through the top port of the column, and (iii) introducing an elution solution for releasing sample components bound to the beads and collecting said components, wherein a magnetic field is not applied to the column, and wherein the beads fanning the fluidized bed are chromatographic support beads which comprises a polymer matrix into which glass or silica particles have been incorporated.
