ABSTRACT:
The invention is directed to an arrangement for measuring the concentration of gaseous or vaporous components of a gas mixture by using optically distinguishable reaction zones from gas test tubes which contain a substance reacting with the component to be detected. The change of the reaction zone is determined by means of direct observation and/or by means of an opto-electronic scanning device. This arrangement is improved in accordance with the invention in that the reacting substance is accommodated at least in one channel formed in a carrier. The channel has a cross section in the reaction zone which is less than 1 mm.sup.2.
