Solid-Contact Reference Electrode for Ion-Selective Sensors
This work presents a flexible miniaturized ion-selective sensor consisting of a solidcontact reference electrode (RE) and ion-selective electrodes (ISE) fabricated on the same foil. The flexible ion sensor was based on AgCl electrodes screen printed on polyethylene terephthalate foil. The RE was formed by casting a mixture of plasticized polyvinylchloride (PVC) and KCl on the AgCl electrode. Th...
متن کاملA Solid-Contact Ion Selective Electrode for Copper(II) Using a Succinimide Derivative as Ionophore
All-solid-state sensors with polyvinyl chloride (PVC)-based membranes using off-the-shelf N-hydroxysuccinimide (NHS) and succinimide (Succ) ionophores were prepared using DOP (dioctyl phthalate) and NPOE (ortho-nitrophenyloctyl ether) as plasticizers. Good responses were obtained when NHS was used. The potentiometric response of the proposed electrode is independent of pH over the range 2-6. Th...
متن کاملEvaluation of a New Solid-State Reference Electrode Junction Material for Ion-Selective Electrodes
The performance and properties of a new low-resistance material, Refex, suitable for use in reference electrode junctions is described. The material is a solid polyvinyl acetate that contains a very large loading of KCl (1: 1 w/w KCl/PVA). Despite relatively large active surface areas in the designs studied (stand-alone reference and combination pH), leakage rates of KC! are remarkably low. pH ...

متن کاملNovel Solid-Contact Ion-Selective Microelectrodes for Localized Potentiometric Measurements
The design and properties of novel type of solid-contact ionophore-based ion-selective microelectrodes are reported. The microelectrode is based on an insulated needle-shaped metallic wire with an exposed apex. The ion-to-electron transducer is made of poly(3-octylthiophene-2,5-diyl) and placed between an ion-selective membrane and the metallic tip. The ion-selective polyvinyl chloride-based me...
