Potentiometric response of an ISE based on a perfluoroperhydrophenanthrene membrane doped with ionophore (1) and anionic sites (71 mol % relative to 1): Response to K+ in the absence of interference ions (open circles) and in the presence of interfering ions (filled circles; 10 mmol L−1 NaCl, 500 mmol L−1 LiCl, 2.0 mmol L−1 NH4Cl, or 1.0 mmol L−1 CsCl).
