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.

Measuring device, reaction carrier and measuring method

An automated analysis method for an impactor used as a measuring transducer for the selective determination of oil mist or aerosols. The process includes the steps of rotating the deflector plate () of the measuring transducer () about the symmetry axis thereof and of determining the quantity of oil deposited by means of an optical analyzing device from the extinction of a light beam reflected from deflector plate () due to the alternation between the background and the pattern produced by the micronozzles ().

Process for the selective determination of oil mist or aerosols

A measuring sensor () for the selective determination of oil mist or aerosols makes possible gas analysis in the ambient air. The measuring sensor () is inserted into an adapter housing (), and a vacuum, by which ambient air is drawn in via the gas inlet duct () of the measuring sensor (), is generated in the adapter housing () by means of a gas delivery pump ().
