ABSTRACT:
Apparatus disclosed herein provide simple means for observing chemiluminescent reactions and for measuring the concentrations of several constituents of a gaseous sample substantially simultaneously, as for example the concentrations of NO.sub.x, NO and NO.sub.2 in a mixture of other gases. Chemiluminescence is induced by the spontaneous reaction of selected constituents with reagents in a plurality of small reaction chambers confronting a single sensitive photodetector. The reation chambers utilize concentric feed nozzles to enhance the intimate mixing of reactants to promote more complete and rapid reaction near ambient pressure in a minimized space.
