Patent ID: 8628652

Claim:
A continuous electrochemical concentrator in an analytical system comprising: (a) a water generator compartment having an outlet, (b) an anode compartment disposed adjacent one side of said generator compartment, (c) a cation exchange barrier separating said generator compartment from said anode compartment, said cation exchange barrier being capable of passing cations but not anions and of blocking bulk liquid flow, (d) a first electrode in electrical communication with said anode compartment, (e) a cathode compartment disposed adjacent said generator chamber, (f) an anion exchange barrier separating said generation compartment from said cathode compartment, said anion exchange barrier being capable of passing anions but not cations and of blocking bulk liquid flow, (g) a second electrode in electrical communication with said cathode compartment, and (h) a detector in fluid communication with said water generator compartment outlet in the absence of a sample injector for the supply of sample, other than sample supplied from said water generator compartment outlet, disposed between said generator compartment outlet and said detector.
