Abstract: A method for measuring of the total content of organic carbon and of nitrogen in water. The total organic carbon value is obtained correctly as the sum of the liquid, dissolved, and solid materials of a sample of the water. The device comprises a non-dispersive infrared (NDIR) gas analyzer for the simultaneous measurement of the concentration of the gas components carbon dioxide CO.sub.2 and nitrogen oxide NO. The NDIR gas analyzer includes a phase separator (50), a thermal reactor (52), a double cooler (70), two valves (54, 56), as well as two amplifiers (58, 60) for the pneumatic signals of the receiver detectors (30, 36) with a display (62. 64) for the measured concentrations, total organic carbon and total nitrogen. The sample is split in a phase separator (50) into a gaseous and into a liquid part. The gaseous part, which comprises substantially the inorganic part of the carbon, the total inorganic carbon part in the form of carbon dioxide CO.sub.2 gas, is cooled in a cooler to such an extent that a substantial part its water vapor content is deposited in the cooler by condensation. The dried gaseous part is led as comparison gas through the comparison cuvette. This step serves to compensate the total inorganic carbon part of the sample and to compensate for unavoidable water vapor cross-sensitivities during the measurement of the carbon dioxide CO.sub.2 concentration and of the nitrogen oxide NO concentration.

Abstract: The sensitivity and selectivity of a two beam analyzer operating with negative filtering and differential absorption-pressure detection is improved by employing differently long cells for the sample gas in the two beam paths, which reduces the effect resulting from overlapping absorption bands of the wanted and of unwanted components in the sample gas.

Abstract: Apparatus for determining the nitrogen oxide concentration in a gaseous mixture while minimizing measuring errors. The radiation from a hollow cathode lamp emitting the nitrogen oxide resonance radiation is modulated by a device for generating alternatively an unfiltered or test beam and a reference beam. The reference beam is filtered by a nitrogen oxide filled filter. An absorption cell is disposed in the path of the reference beam. Further, a monochromator or filter is provided and a detector for receiving the radiation from the monochromator filter. A signal processing unit is coupled to the detector for forming electric signals corresponding to the signal from the unfiltered and the reference beam and for forming the quotient thereof. A ray splitter is disposed in the path of the two beams to provide a different beam path and an additional radiation detector is disposed in the additional path. The signal processing unit has additional means for forming the quotient of the two signals generated by the additional detector and which have not passed the absorption cell. This will then provide an additional quotient of the two available quotients thus minimizing the normally occurring errors.

Abstract: A method for measuring NOx having a specific discharge lamp. The method controls a photometric analysis device, in which an electrically rotatable filter wheel or shutter wheel is used to change various shutters and/or filters in a beam path with beam source, cuvette and detector. The filter and/or shutter wheel is controlled in such a way that the measurement time is greater than the transfer time. This control improves the detection limit of the NOx resonance absorption method.
