Abstract
An indicator phase, luminol immobilized on a strongly basic anion-exchange resin, was evaluated for the chemiluminescence sensing of O2 in N2 gas. The base catalyzed luminol chemiluminescence was monitored with a silicon photodiode installed in a flow cell, into which the luminol-loaded resin was packed. The signal was dependent significantly on resins and solvents used for the immobilization. Oxygen gas concentrations at ppm levels in a N2 gas and a city gas were determined by means of 1 ml sample injection.
