Potentiometric multisensor systems were shown to be very promising tools for the quantification of numerous analytes in complex radioactive samples deriving from spent nuclear fuel reprocessing. Traditional multivariate calibration these is performed with partial least squares regression—an intrinsically linear regression method that can provide suboptimal results when handling potentiometric s...

BACKGROUND The construction and electrochemical response characteristics of Poly (vinyl chloride) membrane sensors for moxifloxacin HCl (MOX) are described. The sensing membranes incorporate ion association complexes of moxifloxacin cation and sodium tetraphenyl borate (NaTPB) (sensor 1), phosphomolybdic acid (PMA) (sensor 2) or phosphotungstic acid (PTA) (sensor 3) as electroactive materials. ...

A dual microelectrode electrochemical time-of-flight technique in which diffusion flux of Ag+, Cl-, or H+ ions electrochemically produced at a generator electrode is measured by recording potential-time transients with Ag, Ag/AgCl, or iridium oxide potentiometric microsensors, respectively, is developed. The generator and microsensor electrodes are typically spaced by 50-100 microm and are inco...

The research on ion-measuring devices has seen a rapid expansion in the last years as consequence of growing interest wearable sensors for biofluids analysis and portable remote or in-line water food quality monitoring. As result, an increasing number researchers is approaching field ion-selective sensors. Despite apparently simple transduction principle, theory behind their working mechanism f...

The fabrication and characterization of potentiometric chalcogenide glass (CG) electrodes with selectivity for bromide in aqueous media are reported. focus is on the production glasses material system AgBr Ag2S As2S3 their investigation by means a series physico-chemical methods, as well aid precision mechanical manufacturing assembly techniques to form usable sensors testing. In addition conve...

The present work aims to develop a sensor that can leave the laboratory and be industrialised. For this reason potentiometric sensors based on a solid electrolyte YSZ and 2 metallic electrodes (platinum and gold) were fabricated by screenprinting technology and were tested in a laboratory test bench for different concentrations of CO, NO and NO2 in oxygen rich atmosphere. By deposing a catalyti...
