Miniature potassium-sensitive electrodes with neutral carriers in a poly(vinyl chloride) matrix.
A miniature version of the potassium ion-selective electrode with valinomycin or dimethyldibenzo-30-crown-10 in a poly(vinyl chloride) matrix is described. Electrodes having an effective membrane area of <0.2 mm(2) exhibit Nernstian behaviour within a range of activities of the potassium ion of 10(-1)-10(-5)M, a rapid response and good long-term potential stability.
