A novel method has been developed for the photometric determination of nitrogen oxides (NO,; NO and NO, gases). The sample .gas is shaken with an NaOH-alkaline H20, solution in a container so that all the NO, is converted to the NO; form. After decomposition of the H,O, by heating, the colour is dev
A rapid, inexpensive on-line technique for the analysis of stable isotopes of oxygen in organic matter and water is described. The oxygen in the sample is pyrolysed over nickelized carbon using a modified Unterzaucher technique and converted to carbon monoxide. Separation of the CO from N 2 by gas c
