Trace-level chronopotentiometric detection in the presence of a high electrolyte background using thin-layer ion-selective polymeric membranes.

We propose here a pulsed galvanostatic control of a solid-contact ion-selective electrode coupled with a thin-layer ion-exchanger free membrane, which allows chronopotentiometric trace-level ion detection with a high-interfering background in a rapid and reversible way. [ABSTRACT FROM AUTHOR]
