Determination of Small Quantities of Nitric Oxide and Nitrogen Dioxide in Nitrogen by Gas Chromatography

Source

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).
