Webplication of the two Metrohm ion-selective sodium electrodes – the 6.0501.100 glass membrane ISE and the 6.0508.100 polymer membrane ISE – are ex-plained in detail. Theory The activity of ions can be determined by means of ion-selective electrodes. In very dilute solutions the activity corresponds approximately to the concentration Web3 nov. 2024 · The ion selective electrode, shown in Figure 3, is separated from the sample by a membrane. The membrane is designed to interact with a specific analyte of interest, e.g. ammonium or nitrate. ISE potential (mV) is affected by changes in the effective concentration of the analyte.
Webnal ion-to-electron layer has improved the potential stability by unblocking the charge transfer at electrode’s interfaces [14–17]. Nevertheless, the inevitable water layer and oxidation reaction with dissolved oxygen between the CPs and ion sensitive membrane limit the practical applica-tion of electrodes modified with CPs-type membranes.
