Title Gas chromatographic method for determination of carbon monoxide and dioxide
Original title Gasohromatografičeskij metod opredelenija oksida i dioksida ugleroda [in Russian]
Bibliographic information Jan. 1987, No.1, p.49-50. Illus. 3 ref.
Abstract The characteristic feature of the method is the preliminary separation of CO and CO2 at room temperature on a short column (45 x 3.5mm), filled with SKT activated carbon (0.25-0.50mm) outside the chromatograph. The separated oxides are converted to methane on a nickel catalyst at approx. 500░C and analysed with a flame-ionisation detector. Hydrogen was used as carrier gas and reducing agent. The minimum detectable amount of oxide is 0.5mg/m3 in a sample volume of 2mL. The method was used to analyse products of out-gassing from coatings containing phenol-formaldehyde resins.
