A reaction carrier (), a measuring device () and a measuring method for measuring a concentration of gaseous/aerosol components of a gas mixture uses reaction material () which reacts in an optically detectable manner with at least one component to be measured or with a reaction product of the component to be measured. The reaction carrier includes a flow channel () with sections () and extends between connecting elements (). A gas treatment element (), in each of the sections, changes chemical or physical properties of the gas mixture flowing therethrough or reacts, depending on the chemical or physical properties. The sections are separated from each other in a gas-tight manner by a separating element (). A coupling element () opens the separating element and establishes a connection between the sections when the coupling element is activated. The measuring device includes an activation element () to activate the coupling element.
