Abstract
A measuring device () and a measuring method measure a concentration of gaseous and/or aerosol components of a gas mixture. A reaction carrier () has a flow channel () defining a reaction chamber () with an optically detectable reaction material () to react with at least one component or with a reaction product of the component. The measuring device () includes a gas delivery unit () and detection unit () having a lighting device () for lighting the reaction chamber (). An optical sensor () detects the reaction. An evaluation unit () evaluates data of the optical sensor () to determines a concentration. The gas delivery unit () includes a gas delivering device () delivering the gas mixture through the gas outlet channel () and a control/regulation unit () which controls/regulates a flow of the gas mixture through the flow channel () depending on at least one reaction speed parameter.
