    • A non-electrolytic method and apparatus for treating an aqueous sample stream including analyte ions and matrix ions of opposite charge, for pretreatment or suppression. The apparatus includes an ion exchange membrane capable of passing only ions of opposite charge to the analyte ions, a sample stream flow channel, a first aqueous stream ion receiving flow channel adjacent one side of the sample stream flow channel and separated therefrom by the first ion exchange membrane, and stationary flow-through ion exchange packing disposed in the sample stream flow channel. The ion receiving channel has an ion exchange capacity for the matrix ions less than about 25% of the ion exchange capacity for the matrix ions.
    • 一种用于处理包含分析物离子和相反电荷的基质离子的水样品流的非电解方法和装置,用于预处理或抑制。 该装置包括能够仅将相反电荷的离子通过到分析物离子的离子交换膜,样品流流动通道,邻近样品流流动通道的一侧的第一含水流离子接收流动通道,并由第一离子 交换膜和设置在样品流流动通道中的固定流通离子交换填料。 离子接收通道对于基质离子的离子交换容量小于基质离子的离子交换容量的约25%。
