MEASURING DEVICE, REACTION CARRIER AND MEASURING METHOD

摘要

The invention relates to a reaction carrier (14), a measuring device (12) and a measuring method for measuring a concentration of gaseous and/or aerosol components of a gas mixture by means of a reaction material (48) which reacts in an optically detectable manner with at least one component to be measured of the gas mixture or with a reaction product of the component to be measured. The reaction carrier (14) comprises at least one flow channel (42) which is subdivided into at least two sections (43) and extends between two connecting elements (44), at least one gas treatment element (47) being provided in each of the at least two sections (43) and changing the chemical or physical properties of the gas mixture flowing therethrough or reacting depending on the chemical or physical properties. At least two sections (43) of the at least one flow channel (42) are separated from each other in a gas-tight manner by a separating element (49) and at least one coupling element (45) is provided and designed to open the separating element (49) and establish a connection between the sections (43) when the coupling element (45) is activated. The measuring device (12) comprises at least one activation element (25) which is designed to activate the at least one coupling element (45) of the reaction carrier (14).
