(EN) METHOD OF ANALYSING CARBON AND CARBON COMPOUNDS
Abrégé
(EN)
A method of and an apparatus for analysing carbon and carbon compounds on heat resistant materials and in composite materials, containing carbon and hydrogen by oxidation of carbon and hydrogen with a gas containing oxygen and determining the water vapor and carbon dioxide contents of the gas. The test material is placed in a first oven (1) in which the temperature is raised such that a regulated temperature rise is obtained and that the test material is subjected to a passing inert gas which is free from carbon and hydrogen, this gas furthermore containing oxygen or is supplied with oxygen after passing the test material, the gas containing oxygen being caused to pass a second oven (4) containing an oxidation catalyst (15) and at a temperature of over 500oC, in that the gas is subsequently cooled to a constant temperature suitable for analysing the gas, after which the water vapor and carbon dioxide contents of the gas are continuously determined and registered in relation to the temperature in the first oven (1).
