Abstract
A measuring device () and a measurement method measure a concentration of gaseous/aerosol components of a gas mixture. A reaction carrier () has a flow channel () defining a reaction chamber () having a optically detectable reaction material (), that reacts with a gas mixture component or with a reaction product. The measuring device () includes a gas-conveying assembly () with a gas-conveying apparatus () conveying the gas mixture and a detection assembly (), which has a lighting apparatus () for lighting the reaction chamber (), an optical sensor () for sensing the optically detectable reaction, and an evaluating unit () evaluating sensor data and determining a concentration of the component of the gas mixture. The detection assembly () senses a speed of a reaction front () propagating in the flow direction in the reaction chamber () and determines a preliminary concentration from the speed of the reaction front ().
