N2 in a gas phase sample is described. The nitrogen is transformed by a microwave discharge into nitric oxide NO. The latter is analyzed by recording both a 15NO and a 14NO Faraday LMR signal. The determination of the transformation rate from N2 into NO is described. The method of measurement and the achieved sensitivity (∼0.1 ppm 15N2≈4 nanomoles 15N2/litergas) of the spectrometer are discussed. An application in pharmacology, where 15N is used as a tracer for metabolism is indicated. First experiments with the exhalation of a rat show that the apparatus is useful to give a new quality of results.
