Lub plawv ntawm cov potassium ISE niaj hnub no feem ntau yog cov kua membrane ua los ntawm polymer lossis cov PVC membrane ua los ntawm valinomycin. Valinomycin, ib qho ionophore ntuj, qhia txog kev xaiv tshwj xeeb rau cov potassium ions dua li lwm cov cations xws li sodium (Na⁺), uas yog qhov tseem ceeb rau kev ntsuas qhov tseeb hauv cov matrices nyuaj xws li cov ntshav lossis cov av rho tawm. Lub electrode ua haujlwm ntawm lub hauv paus ntsiab lus potentiometric: thaum muab tso rau hauv ib qho qauv, qhov kev sib txuas xaiv ntawm K⁺ ions ntawm qhov sib txuas membrane-solution tsim qhov sib txawv ntawm qhov ntsuas tau. Lub peev xwm no, ntsuas tawm tsam lub electrode siv ruaj khov, ua raws li Nernst equation thiab yog logarithmically proportional rau potassium ion kev ua ub no.
