    Abstract

    Studies were made on the determination of nitric oxide (NO) and nitrogen dioxide (NO2) present at less than 5000 ppm by volume in nitrogen. The work was a continuation of previous studies on the quantitative analysis of small amounts of nitric oxide in nitrogen by gas chromatography using a silica gel column. The nature of the results suggests that NO and NO2 are irreversibly adsorbed in small quantities on silica gel. This strong adsorption, separate from a physical or van der Waals adsorption, forms a basis for separation of small amounts of NO and NO2 subsequent to an initial conditioning of the silica gel with these oxides of nitrogen (N2).
