Abstract

A suppressor for use in ion chromatography including at least an effluent flow channel separated by a charged membrane from a suppressor flow channel. A screen of the same charge as the membrane is placed in at least the effluent flow channel. Preferably, a similar screen is placed in the regenerant flow channel. The screen increases the dynamic capacity of the membrane suppressor.
