摘要： An electrolytic suppressor (22) including (a) a suppressor bed (26) of ion exchange resin, (b) an electrode chamber (44) adjacent the suppressor, (c) a first electrode (42) in the electrode chamber, (d) a barrier (40) separating the suppressor bed from the first electrode chamber preventing significant liquid flow but permitting transport of ions only of the same charge as the suppressor bed resin, (e) a second electrode (36) in electrical communication with the resin bed, and (f) a recycle conduit (30, 32, 34, 38, 48) between the suppressor outlet port and said electrode chamber. The second electrode may be in contact with the ion exchange resin in the suppressor or located in second electrode chamber. For anion analysis, the method of using the apparatus includes: (a) flowing an aqueous liquid sample stream containing anions to be detected and cation hydroxide through the separator bed, (b) flowing the aqueous effluent from the separator bed through the flow-through suppressor, (c) flowing the effluent liquid from the suppressor past a detector, (d) recycling said liquid effluent from the detector through a cathode chamber proximate to the suppressor bed and separated by the first barrier, and (e) applying an electrical potential between the cathode and the anode. Water is electrolyzed at the anode to cause cations on the cation exchange resin to electromigrate toward the barrier and to be transported across the barrier toward the cathode while water in the cathode chamber is electrolyzed to generate hydroxide ions which combine with the transported cations to form cation hydroxide in the cathode chamber.

摘要： Method and apparatus are provided for electrochemically generating an acid or base eluent in an aqueous solution and for simultaneously suppressing conductivity of the eluent in an ion exchange bet (30) after chromatographic separation in an ion chromatography system. The suppressor and eluent generator includes a flow-through suppressor bed (30) of ion-exchange resin, having an inlet (28) and an outlet section (34). An electrode chamber (14) adjacent the suppressor bed inlet section (28) includes a first electrode (17). A barrier (40) separates the suppressor bed (30) from the electrode chamber (14) and prevents significant liquid flow but permits transport of ions only of the same charge as said suppressor bed resin exchangeable ions. A second electrode (32) is in electrical communication with said suppressor outlet section (34). The sample flows through a chromatographic column (26) and then through the suppressor bed (30) to the detector (36). Acid or base generated in the chamber (14) flows to the separator bed (30) and serves as the eluent for chromatographic separation.

摘要： An electrolytic eluent generator system includes a flow-through eluent generating zone, a first reservoir comprising configured to hold a first ion source; a second reservoir configured to hold a second ion source; a first ion exchange connector disposed between the first reservoir and the eluent generating zone, wherein the connector substantially prevents liquid flow through the ion exchange connector and transports ions only of the same charge as said first ions; and a second ion exchange connector disposed between the second reservoir and the eluent generation zone, wherein the connector substantially prevents liquid flow through the ion exchange connector and transports ions only of the same charge as said second ions. The second ion exchange connector is of opposite charge to the first ion exchange connector.

摘要： Method and apparatus for generating an acid or base, e.g., for chromatographic analysis of ions. For generating a base, a cation source, such as a salt, cation hydroxide or cation exchange resin, is provided in a cation reservoir (10) separated from a base generation chamber (12) by a permselective barrier (14). An aqueous stream (21) flows through the base generation chamber (12) containing a cation exchange material (19). An electric potential is applied between an anode (16) in the cation source reservoir (10) and a cathode (18) in the base generation chamber (12) to electrolytically generate hydroxide ions and cause cations in the reservoir (10) to electromigrate through the barrier (14) toward the cathode (18) to combine with the migrated cations to form cation hydroxide, which flows from the base generation chamber (12).
