Described is a device for a gas analysis, for determination of the content of two or more gases in a gas flow, comprising at least one source (3) for emission of two or more ray paths (2) of radiation of a detectible wavelength, a cuvette device having an inlet (18) and an outlet (19) for the gas flow, a filter (23) for transmission of radiation of a characteristic wavelength for the respective gas and a detector device comprising a plurality of detectors (22) for conversion of the radiation into an electrical signal, characterized in, that the cuvette device comprises a block (1) with a number of through-going cuvettes (14) in each of the ray paths, which cuvettes are interconnected by channels (15,16,17) which connect the ends of the cuvettes, to the formation of an unbroken conduit for the gas flow from the inlet to the outlet, and in that a first (12) and a second (13) cuvette window, which cuvette windows are transparent for the radiation to be detected, are arranged to the block over each end of the cuvette device in the ray path from the source, adjacent to which second cuvette window the detectors are arranged. <IMAGE> |
