Abstract:
1. An apparatus for analyzing chemical species comprising: a. at least one membrane assembly each comprising a semipermeable membrane, a first flow channel having a first flow channel inlet and a first flow channel outlet, a second flow channel having a second flow channel inlet and a second flow channel outlet, said semipermeable membrane separating said first and said second flow channels, and an electrode positioned in said second flow channel, b. during operation of the apparatus, a first and a second solution flow in said first and said second flow channels, respectively, c. means for regulating a pressure gradient across said semipermeable membrane between said first and said second flow channels of said at least one membrane assembly; d. means for introducing sample species into said first solution, e. a detector responsive to at least a portion of said sample species flowing from said first flow channel outlet of said at least one membrane assembly, and f. at least one means for capturing, releasing, or separating said portion of said sample species in said first solution, said means connected to said first solution flow.
