Abstract
An apparatus for capillary ion chromatography having a suppressor having flow-through ion exchange packing in a housing and capillary tubing formed of a permselective ion exchange membrane, and at least partially disposed in said ion exchange packing. Also, a recycle conduit for aqueous liquid from the detector to the packing. Further, the capillary tubing may have weakly acidic or weakly basic functional groups. Also, a method for using the apparatus.
