Spray-coated all-solid-state potentiometric sensors.
A novel fully spray coating-based method of the preparation of all-solid-state ion-selective electrodes of simplified construction is proposed. This method is an alternative for screen-printed electrodes used sometimes in potentiometric applications. The benefits of the herein-proposed approach include fully automatic sensor preparation and minimized use of chemicals allowing for the production...
متن کاملPotentiometric determination of Benzydamine hydrochloride using PVC membrane and coated wire sensors in pure form, pharmaceutical compounds and biological fluids
The construction and electrochemical response characteristics of PVC membrane and coated wire sensors for the determination of Benzydamine hydrochloride (Benz) are described. PVC membrane sensors, include sensors 1, 2 and 3, and coatedwire sensors include sensors 4, 5 and 6. Sensors 1 and 4 based on benzydamine phosphotungstate (Benz-PTA) as ion-pair, sensors 2 and 5 based on benzydamine phosph...
متن کاملNew Coated Wire Sensors for Potentiometric Determination of Gemifloxacin in Pure Form, Pharmaceutical Formulations and Biological Fluids
A simple, accurate and precise potentiometric method was developed for the determination of gemifloxacin mesylate (GFX). Three ion selective coated wire sensors have been constructed from the incorporation of (GFX) with the ion-pairing agents phosphotungstic acid (PTA), phosphomolybdic acid (PMA) and Ammonium reineckate salt (ARS). The three sensors show nearly Nernestian response over the conc...
متن کاملPotentiometric Flow Injection Analysis of Bromhexine Hydrochloride and its Pharmaceutical Preparation Using Conventional and Coated Wire Ion-Selective Electrodes
Bromhexine hydrochloride ion-selective electrodes (conventional type) based on bromhexinium tetraphenyl borate (I) and bromhexinium-phosphotungstate (II) were prepared. The electrodes exhibited mean slopes of calibration graphs of 59.4 mV and 59.8 mV per decade of bromhexine concentration at 25 C for electrode (I) and (II), respectively. Both electrodes could be used within the concentration ra...
متن کاملNew conventional coated-wire ion-selective electrodes for flow-injection potentiometric determination of chlordiazepoxide.
New chlordiazepoxide hydrochloride (Ch-Cl) ion-selective electrodes (conventional type) based on ion associates, chlordiazepoxidium-phosphomolybdate (I) and chlordiazepoxidium-phosphotungstate (II), were prepared. The electrodes exhibited mean slopes of calibration graphs of 59.4 mV and 60.8 mV per decade of (Ch-Cl) concentration at 25 degrees C for electrodes (I) and (II), respectively. Both e...
