| Abstract | Nitric oxide (NO) and nitrous oxide (N2O) are two important trace gases in the atmosphere. Determining the concentration and 15N abundance of NO and N2O in air is difficult owing to their very low concentration in the atmosphere (NO < 1 ppb(v); N2O ≈ 0.32 ppm(v)). Although 15N analysis of N2O in ambient concentrations can be carried out using a gas chromatograph quadrupole mass spectrometer system (GC-QMS) and a dosage of 2 mL of air by means of a sample loop, this system is not sensitive enough to measure the ambient concentration of NO and its 15N abundance. Therefore the concentration of NO must be enriched by cryotrapping (cooling with liquid nitrogen). The 15N analytical method developed enables the sensitive and sufficiently precise measurement of 15N-enriched NO in air. Furthermore, the analytical equipment developed greatly improves existing 15N2O analysis using the GC-QMS technique. An application of the 15N analysis method will be shown for an investigation on the NO and N2O formation in black earth soil after 15NH4+, 15NO3− and 15NO2− labelling. |
