Patent ID: 8597571

Claim:
An integrated suppressor and eluent generator apparatus for ion chromatography comprising (a) a suppressor chamber comprising ion exchange material and including an inlet and an outlet, (b) a first electrode chamber comprising a first electrode and including an inlet and an outlet, (c) a second electrode chamber comprising a second electrode and including an inlet and an outlet, (d) an eluent generator chamber comprising flow-through ion exchange material and including an inlet and an outlet, (e) a first barrier preventing significant liquid flow, but permitting transport of ions of only one charge, positive or negative, disposed between said eluent generator chamber and said second electrode chamber, (f) a second barrier preventing significant liquid flow, but permitting transport of ions of only one charge, positive or negative, disposed between said suppressor chamber and said eluent generator chamber, (g) an eluent recycle conduit providing fluid communication, directly or indirectly, between said suppressor chamber and said eluent generator chamber, (h) an electrode rinse conduit disposed between said first and second electrode chambers isolated from said eluent recycle conduit and (i) a third barrier preventing significant liquid flow, but permitting transport of ions of only one charge, positive or negative, disposed between said first electrode chamber and said suppressor chamber.
