VERFAHREN ZUR BESTIMMUNG DES ANORGANISCHEN KOHLENSTOFFGEHALTES VON WAESSRIGEN FLUESSIGKEITEN

摘要

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 CO2 analyser. The reaction chamber is preferably heated to a temperature of approximately 140 DEG C.
