摘要： 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.
