Abstract
A device for detecting gaseous and vaporous components of a gas mixture by means of channels 2, which are located next to each other on a support 201, are connected in parallel in terms of flow, and are exposed to the component to be detected along a flow axis 3. A scanning section 6 of a scanning device is provided which extends along one of the channels 2, for detecting the change in color of reaction zones in the channels 2. Multiple channel arrangements can also be analyzed in a simple manner with a scanning section evaluating individual channels. At least some of the channels 2 on the support 201 are directed such that an angle .alpha. not equal to 0 is formed between the flow axis 3 and the scanning section 6, and the channels 2 are located in the covered area of the scanning section 6.
