Abstract : Nitrogen-14 signal intensity measurements were taken. From wet chemical analyses, total nitrogen concentrations per unit volume were computed. The high degree of correlation between total nitrogen per unit volume and NSR signal intensities from these samples demonstrates that nitric acid together with oxides of nitrogen are being measured. The random nature of deviations in the correlation plot suggests that the accuracy of NSR in total nitrogen determinations is limited only by the precision to which these measurements can be made.
