Abstract
This paper gives a method to trace quantitatively small quantities of oxygen (down to 10-3 parts in 1) in mixtures of oxygen and nitrogen. This is based on the effect of the ionization of oxygen molecules in a mixture of oxygen and nitrogen by radiation emitted by nitrogen molecules with ionization potentials UO₂ < UN₂ and the energy of radiation between UO₂ and UN₂. Coefficients of absorption and intensities of this ionizing radiation are given in dependence on the concentration of oxygen. A radiation emitted by nitrogen and ionizing nitrogen itself is traced and its coefficient of absorption (μ ≈ 750 cm-1) and its intensity are measured.Keywords
