Combination ion-selective electrode with a replaceable sensing membrane |
摘要 |
An improved combination ion-selective electrode apparatus is provided that comprises an electrode body, a reference electrode, and an ion-sensing electrode. The reference electrode comprises a ion-permeable junction. A removable membrane cap contains a ion-selective membrane. The membrane cap can be removed from the ion-selective electrode apparatus without endangering the integrity of the reference electrode and is distinct from the ion-permeable junction. The membrane cap contains a removable ion-sensitive membrane that can be replaced if the ion-sensitive membrane fails to thereby place the combination ion-selective electrode apparatus back into service. Moreover, a single combination ion-selective electrode apparatus can be used to measure a variety of analyte ions by simple replacement of the membrane cartridge.
