    Abstract: An analyzer for measuring the combined NO and NO.sub.2 concentrations includes a hollow cathode lamp with nitrogen/oxygen filling emitting radiation which is alternatingly passed through two narrow-band interference filters, one having a transmission range clearly outside any NO absorption bands and its NO.sub.2 absorption equals the difference of the absorption coefficients for NO and NO.sub.2 in the transmission band of the other filter. These two beams pass through a measuring gas cell and are photoelectrically detected for further processing.

    Abstract: A photometer for measuring gas components. The photometer has an infrared radiator with radiator modulation, a measuring cell with a measurement and comparison chamber, and a detector which absorbs optopneumatically onto the gas component X, that is filled with gas component X. In order in the case of a photometer of this type to render it possible for a plurality of gas components to be measured with high accuracy and the smallest possible outlay in apparatus, at least one further detector is arranged downstream of the first detector. For the purpose of measuring the gas component Y the further detector is filled with its isotope Y*, and the first detector is optically transparent with regard to the further gas component Y* to be measured or the characteristic absorption bands thereof.

    Abstract: The invention relates to a process for Fabry-Perot spectroscopy using a spectrometer in the radiation path of which there is a radiation source, two successive Fabry-Perot interference filters through which the radiation passes, a blend of substances to be examined and a detector. The optical layer thickness of the first Fabry-Perot filter F1 is set to a given value and the optical layer thickness of the second Fabry-Perot filter F2 is modulated. The resultant interferogram as a function of the layer thickness is characteristic of the substance to be examined. The interferogram received at the detector D is converted by a mathematically transformation into a spectrum as a function of wave numbers.
