ABSTRACT:
A system for pretreating sample streams including a concentrated matrix compound to neutralize the compound. The system includes an electrochemical membrane device in which sample flows through a sample flow channel of the device separated from a matrix ion receiving flow channel by an ion exchange membrane preferentially permeable to ions of the opposite charge to the ions to be analyzed. The ionic species in the thus-pretreated sample are directed to an analytical system such as an ion chromatograph.
