Different membranes were tested on screen printed electrodes to improve signal quality when sensing oxygen at a -700 mV potential (vs Ag/AgCl). The use of a cellulose acetate membrane, drugged with quaternary ammonium salts to provide the necessary electrolyte, allows for a sensible reduction of noise for measurements at negative potentials.

Abstract
Different membranes were tested on screen printed electrodes to improve signal quality when sensing oxygen at a -700 mV potential (vs Ag/AgCl). The use of a cellulose acetate membrane, drugged with quaternary ammonium salts to provide the necessary electrolyte, allows for a sensible reduction of noise for measurements at negative potentials.File in questo prodotto:
