Abstract
In a method for determining the inorganic carbon content of aqueous liquids, the liquid sample together with a carbon dioxide free carrier gas is injected vertically from top to bottom in to a heated reaction chamber. The reaction chamber is filled with liquid phosphoric acid. The carbon dioxide generated in the reaction of the sample with the phosphoric acid is fed to a CO.sub.2 analyser. The reaction chamber is preferably heated to a temperature of approximately 140.degree. C.
Claims7
A method for determining the inorganic carbon content of aqueous liquids, wherein a liquid sample to be analysed is injected vertically downwards into a reaction chamber containing liquid phosphoric acid, into which is also fed a carbon dioxide-free carrier gas, the sample reacting with the phosphoric acid to form carbon dioxide and water and the carbon dioxide generated is fed to a carbon dioxide analyser.
