“…(d) Mo (Goodfellow, 99.95%, OD 0.25 mm) was used for the reduction of NO 2 to NO. NO 2 is a reactive gas and has poor chromatographic performance. ,, Mo was chosen for the precolumn reduction of NO 2 to NO because it is already commonly used for detection of NO x by chemiluminescence, a robust and routine method in environmental analysis…”

Methods were developed for the on-line analysis of stable isotopes of nitrogen (at natural abundance levels) in NH(3), NO and NO(2) in order to study the contribution of these trace gases to nitrogen cycling in ecosystems. Standard methods for the combustion of organic substances to N(2) (for the determination of the (15)N/(14)N ratios by mass spectrometry) failed to satisfactorily oxidize or reduce the respective trace gases. The following oxidation or reduction techniques ensured quantitative conversion of the trace gases to N(2) and analytical precision close to the internal precision of the instrument (precision ±0.15‰): (1) oxidation of NH(3) to N(2) at 1150 °C on a NiO surface (which needs a reoxidation before each NH(3) analysis; measuring range 11.7-58.8 nmol of NH(3), precision ±0.30‰); (2) reduction of NO to N(2) at 1150 °C on a Ni surface (measuring range 33.3-133.3 nmol of NO, precision ±0.28‰); (3) reduction of NO(2) to form NO at 420 °C on a Mo surface followed by further treatment as for NO (measuring range 26.0-129.9 nmol of NO(2), precision ±0.90‰). This last technique was developed due to the poor chromatographic properties of NO(2).

Mass spectrometry is not able to differentiate NO x and N 2 from other interferences (e.g. CO and C 2 H 4 ) in the deNO x reactions. In the present study, a quantitative method for analysis of NO x and N 2 simultaneously in these reactions with an assisted converter operated at higher temperature under O 2 -rich condition, which eliminates the interferences, is developed. The NO x conversion from this method is comparable to the one from an Automotive Emission Analyser equipped with NO x electrochemical sensor. Two types of deNO x reactions are tested in terms of selectivity of N 2 production. The application of this method is discussed.
