Web30 sep. 2015 · Dear Colleagues, Ionophore-based potentiometric sensors or ion-selective electrodes (ISEs) are chemical sensors where host-guest chemistry is utilized to achieve high selectivity to specific ions of interest. A unique feature of ISEs is that they provide information about the free ion concentration (ion activity), which is highly relevant in, e ... WebSelectivity coefficients An electrode used to measure ion A selectively may also slightly responds to ion X. For instance, a pH electrode responds to Na + when [H +] 10-12 M and [ Na +] 10-2 M. The smaller the selectivity coefficient is, the less is the interference by X . The response of an I.S.E. is thus represented by = ± +∑ X z A A X X
