Abstract:  A method of quantitative elemental analysis based on the catalytic oxidation of organic substances in evacuated glass ampoules in the presence of CuO at 550°C is described. Nitrogen, carbon dioxide, and water vapour formed are dosed into a gas Chromatograph by means of a device which breaks off the ends of ampoules. Then these substances are separated on a column with a Chromosorb 102 using hydrogen as a carrier gas. The accuracy, precision, and sensitivity of this method are evaluated and some examples of the analysis of different kinds of nitrogen-containing compounds, of the identification of polymers, and the characterization of gas-chromatographic fractions are presented.
