A fixed bed () is provided for a fixed-bed reactor (). The fixed bed () contains a particulate carrier and at least one reactive substance. The carrier is a silicate compound and the reactive substance is an organometallic pyridine compound. A method for preparing such a fixed bed is provided. The method includes the steps of preparing the carrier, preparing an impregnation and treating the carrier with the impregnation. In addition, a gas-measuring tube is provided with a correspondingly prepared fixed bed as well. A method uses organometallic pyridinium compounds, especially pyridinium dichromate, in a fixed-bed reactor for detecting alcohol compounds and for preparing formaldehyde and/or acetaldehyde.

A magazine device () and method are provided for a measuring device () for measuring a concentration of gaseous and/or aerosol components of a gas mixture. The magazine device () includes a holding device () for a plurality of reaction carriers (), which have each at least one reaction chamber with a reactant. The reactant is designed to react with a particular component to be measured in the gas mixture or with a reaction product of the component to be measured in an optically detectable manner. A feed device () removes a reaction carrier () of the plurality of reaction carriers () from the holding device () and feed the reaction carrier to the measuring device () for carrying out a measurement of the particular component to be measured in the gas mixture. A control unit () controls the holding device () and/or the feed device ().
