Potentiometric Ag+ response with the lowest detection limit achieved in this work, as recorded after conditioning of the electrode in 1 μM AgNO3 for 2 days and 1 nM AgNO3 for another 2 days. The fluorous membrane was composed of the linear perfluorooligoether 2, doped with 0.5 mM borate salt 3, and 1.5 mM ionophore Ag-4. The solid line is a fit based on the Nicolskii–Eisenman Formalism6 and the interrupted lines show how the detection limit was determined according to IUPAC recommendations.55
