Gas Chromatographic Determination of Total Oxygen in Organic Materials
A sample is pyrolyzed in the presence of carbon to quantitatively convert oxygen to carbon monoxide. Helium elutes the pyrolysis products through a molecular sieve column for separation of the carbon monoxide and through a katharometer for quantitative measurement. Analysis time is 15 — 30 min, detectability is 30 ppm, no blank is involved, and less than 50 mg of sample is used.
