    摘要: 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.

    摘要: A liquid chromatographic system is provided including catalytically combining hydrogen and oxygen gases in the chromatography eluent stream in a catalytic gas elimination chamber, to form water and thereby reduce the gas content in the eluent stream. Also, a liquid ion chromatographic system in which the effluent from the detector is recycled to a membrane suppressor and then is mixed with a source of eluent for recycle to the chromatographic column.
