Abstract
An analytical device for determining a measured variable dependent on the concentration of one or more constituents of a sample includes a decomposition reactor surrounded by an insulating tube, a heating apparatus, an oxygen production system including at least one oxygen permeable membrane, a housing, and a feed gas guiding system for supplying a feed gas to the at least one membrane of the oxygen production system. The feed gas guiding system includes a reaction space surrounding the at least one membrane and is connected with an inflow duct open to the environment such that at least two partitions are arranged coaxially within the insulating tube and surrounding the decomposition reactor, where the partitions subdivide an intermediate space arranged between the decomposition reactor and the insulating tube into annular chambers forming the feed gas guiding system, where the annular chambers are connected with one another by overflow openings.
