El = Eo By subtracting the second equation from the first, we obtain: A E = El - E2 = Slog ([OX]I/[OX]~) Now, if [Ox12 is kept constant (perhaps at a reference concentration), we then obtain: A E = constant + S log [Ox] where the constant is -Slog [OX]~.
These all introduce complications. In itself the technique has no selectivity. It can be used in controlled situations but really needs to have selectivity superimposed by means of a membrane or coating. 18 A conductivity bridge.

0 John Wiley & Sons Limited. Reproduced with permission. The measurement of conductance involves an alternating current, as in the classical conductance bridge. Varying the frequency of the alternating current can extend this. The quantity measured is then the admittance = Mmpedance), which not only depends on simple conductance but also on the capacitance and inductance of the system. 19. Such diagrams are sometimes called admittance (impedance) spectra. This approach has not so far been used to any great extent in developing sensors and biosensors, but is now receiving increased attention.
