Abstract of the Disclosure Packing tubular membranes or membrane channels for Ion Chromatography with inert particles greatly increases overall suppressor efficiency. The length of membrane required is reduced, e.g. from 20 feet to 5 feet and bandspreading is reduced from 870µl to 200µl. This significant increase in efficiency is attributed to the mixing action of the packing on the flow stream which results in convective radial transport much more rapid than the diffusion controlled transport observed in unpacked membranes. The technique is also described for developing more efficient liquid chromatographic post-column reactors for adding reagent to the column effluent to increase detection sensitivity.
