摘要: 设计了多元叠层型串联ISE,结构紧凑,组装简便,适用于微体积样液分析。对四元叠层型串联ISE的试验表明:与现行ISE比较,其线性响应斜率、测定精密度与灵敏度均增大4倍,但响应速度、选择性系数与检测下限不变。

关键词: 叠层型串联ISE, Nernst倍增效应

Abstract: Multilayer ISEconnected in series was designed and it has been proved both theoretically and experimentally that the response slope, sensitivity and precision in the potentiometric determination can be raised by n-times by using the proposed multilayer ISE (n = 4) connected in series in comparison to the usual ISE, while the response time, electrode selectivity and detection limit remain the same as the usual ISE.

Key words: Multilayer ISE connected in series, Effect of Nernst multiplication
